This book is focused on recent progress in the dynamically
developing field of controlled/living radical polymerization. It is
a sequel to ACS Symposium Series 685, 768, 854, and 944. Volume
1023 contains 26 chapters on mechanistic, synthetic and materials
aspects of ATRP. Volume 1024 contains 24 chapters on other
controlled/living radical polymerization techniques.
This volume consists of written chapters taken from the
presentations at the symposium "100+ Years of Plastics: Leo
Baekeland and Beyond," held March 22, 2010, at the 239th ACS
National Meeting in San Francisco. The symposium celebrates the
100th anniversary of the formation of General Bakelite Corp., which
was preceded by Leo Baekland's synthesis of Bakelite in 1907 and
the unveiling of the Bakelite process in 1909. It is quite
reasonable to use the synthesis of Bakelite as the starting point
of the Age of Plastics. Indeed, Time magazine in its June 14, 1999,
issue on the 100 most influential people of the 20th century chose
Leo Baekeland and his Bakelite synthesis as the sole representative
of chemistry.
Leo Baekeland and Bakelite are the topics of the first four
chapters of this volume. The first two chapters come from the
perspective of Baekeland family members. Carl Kaufmann is related
to the Baekeland family through marriage and is the author of the
only full-length biography of Baekeland, published as a master's
thesis from the University of Delaware. As a family member Kaufmann
had access to all of Baekeland's papers. This first chapter (Leo H.
Baekeland) is not only a biographical sketch, but an exploration of
Baekeland's effect on the chemical industry. Hugh Karraker is
Baekeland's great-grandson, and his chapter (A Portrait of Leo H.
Baekeland) provides a family picture of the great inventor. Gary
Patterson's chapter (Materia Polymerica: Bakelite) goes into the
history of Bakelite chemistry, while Burkhard Wagner's contribution
(Leo Baekeland's Legacy-100 Years of Plastics) covers the history
of Bakelite manufacture through time and space, finishing with a
description of another Baekeland legacy, the Baekeland Award given
through the North Jersey Section of the ACS.
In later chapters, Les Sperling (History of Interpenetrating
Polymer Networks Starting with Bakelite-Based Compositions) covers
the improvements in interpenetrating networks. James Economy and Z.
Parkar (Historical Perspectives on Phenolic Resins and
High-Temperature Aromatic Polyesters of p-Hydroxybenzoic Acid and
Their Copolyesters) follow the paths of resoles, novolaks, and
related chemicals.
This book will explore our forests as the most readily available
and renewable source of carbon as well as the building block of
chemicals, plastics, and pharmaceuticals as the next 100 years
gradually push consumers toward alternate sources of chemicals.
Meeting these needs from trees requires that new chemistry be
developed so that plant materials is converted to commodity
chemicals. This focused discussion on ongoing global efforts at
creativity using forest and biomass based renewable materials will
include six different mechanisms for bringing about change on this
very innovative topic.
This ACS Symposium Series is the product of a symposium held at the
241st National Meeting of the American Chemical Society in Anaheim,
CA on March 27-31, 2011. It includes chapters on new biobased
building blocks such as the furandicarboxylic acid, polyesters and
polyamides from adipic, succinic and sebacic acids with aliphatic
diols such as 1,3-propylene glycol, 1,4-butanediol,
1,12-dodecylenediol and isosorbide. The conversion of
hydroxymethylfurfural, the dehydration product of hexose sugars, to
succinic acid and 1,4-butanediol to produce poly(butylene
succinate) is described in one chapter. Also the synthesis of new
polymers from plant-derived olefinic monomers such as tulipalin A
and studies of composites from cotton by-products are featured in
other chapters. There is a strong emphasis on biocatalytic
synthesis and polymerization within the book. Chapter topics
include the synthesis of ?-hydroxyfatty acids and polymers
therefrom, an interesting discussion on the structural differences
of the products of the biocatalytic and chemical catalytic
synthesis of polyesters from oleic diacid and glycerol and the
ability to produce polylactic acid (PLA) and PLA-PHA copolyesters
within a "microbial cell factory". Other areas of interest explored
in other chapters include recent developments of biobased polymer
fibers and oleate-based pressure sensitive adhesives and
composites. One chapter describes a large increase in cold-drawn
fiber tensile strength by the blending of a small amount of
ultrahigh molecular weight (MW) poly(3-hydroxybutyrate) with a much
lower MW 3-hydroxybutyrate polymer. The addition of a rubber and
inorganic fillers to normally brittle PLA was found to dramatically
improve its ductility. Finally, there are several chapters on seed
oil-based polyurethanes, one on fibers from soy proteins and
composites from starch.
Both technically and economically, additives form a large and
increasingly significant part of the polymer industry, both
plastics and elastomers. Since the first edition of this book was
published, there have been wide-ranging developments, covering
chemistry and formulation of new and more efficient additive
systems and the safer use of additives, both by processors in the
factory and, in the wider field, as they affect the general public.
This new edition follows the successful formula of its
predecessor, it provides a comprehensive view of all types of
additives, concentrating mainly on their technical aspects
(chemistry/formulation, structure, function, main applications)
with notes on the commercial background of each. The field has been
expanded to include any substance that is added to a polymer to
improve its use, so including reinforcing materials (such as glass
fibre), carbon black and titanium dioxide.
This is a book which has been planned for ease of use and the
information is presented in a way which is appropriate to the
users' needs.
In this volume, inorganic, organic, and bioorganic chemistry are
represented in contributions from around the world. Pioneering work
in self-assembled structures organized by the use of transition
metals is described in chapter 1, followed by details of extensive
studies of self-assembled structures formed from various
biomolecules in chapter 2. The next two chapters describe the
formation of spherical molecular containers and their understanding
of such structures based on Platonic and Archimedean solids, and
the fascinating family of synthetic peptide receptors and the
interactions that can be explored using these host molecules. In
chapter 5 a mixture of computational chemistry, drug design, and
synthetic organic and inorganic chemistry in the development of
superoxide dismutase mimics is described. The final two chapters
discuss the bioorganic and supramolecular principles required for
the design of synthetic artificial enzymes, and the supramolecular
self-assembly and its possible role in the origin of life.
It is hoped that this broad, international view of supramolecular
chemistry and the many directions it leads will be of interest to
those already in the field. It is also hoped that those outside the
field may see extensions of their own work that will bring them
into it.
Volume 13 of this series presents five timely reviews of research
on alkaloids such as new developments in the chemistry and biology
of alkaloids from amphibian skins. It provides a synopsis and
tabulation of the hundreds of alkaloids that have been detected,
with an emphasis on occurrence, structure, dietary origins, and
biological activity.
Alkaloids containing the 1, 2, 3, 3a, 8, 8a - hexahydropyrrolo
2,3b] indole ring system and the cyclotryptamines are discussed. An
exhaustive list of available structures is provided. The chemical
and biological structures have been evaluated critically so as to
identify existing errors and expose irregularities in appearance or
biological function. In addition, attention is drawn to the
possible implications of the accumulated knowledge related to the
synthesis, occurrence, and biochemistry of this class of
alkaloids.
Recent work on alkaloids containing the comparatively non basic
pyrrole ring system is summarized. One of the chapters covers
isolation, structure elucidation, biological activity, and selected
chemical syntheses of certain pyrrole alkaloids.
Recent developments in the chemistry of diterpenoid and
norditerpenoid alkaloids occurring in "Aconitum, Delphinium and
Consolida" genera of the Ranunculaceae family used in Chinese and
Indian medicine are surveyed and the book ends with a focus on
transition metal catalyzed carbonylations as efficient and novel
approaches to the construction of piperidine, izidine and
quinazoline alkaloids, which occur in great numbers in
nature.

This text provides a uniform and consistent approach to diversified
problems encountered in the study of dynamical processes in
condensed phase molecular systems. Given the broad
interdisciplinary aspect of this subject, the book focuses on three
themes: coverage of needed background material, in-depth
introduction of methodologies, and analysis of several key
applications. The uniform approach and common language used in all
discussions help to develop general understanding and insight on
condensed phases chemical dynamics. The applications discussed are
among the most fundamental processes that underlie physical,
chemical and biological phenomena in complex systems.
The first part of the book starts with a general review of basic
mathematical and physical methods (Chapter 1) and a few
introductory chapters on quantum dynamics (Chapter 2), interaction
of radiation and matter (Chapter 3) and basic properties of solids
(chapter 4) and liquids (Chapter 5). In the second part the text
embarks on a broad coverage of the main methodological approaches.
The central role of classical and quantum time correlation
functions is emphasized in Chapter 6. The presentation of dynamical
phenomena in complex systems as stochastic processes is discussed
in Chapters 7 and 8. The basic theory of quantum relaxation
phenomena is developed in Chapter 9, and carried on in Chapter 10
which introduces the density operator, its quantum evolution in
Liouville space, and the concept of reduced equation of motions.
The methodological part concludes with a discussion of linear
response theory in Chapter 11, and of the spin-boson model in
chapter 12. The third part of the book applies the methodologies
introducedearlier to several fundamental processes that underlie
much of the dynamical behaviour of condensed phase molecular
systems. Vibrational relaxation and vibrational energy transfer
(Chapter 13), Barrier crossing and diffusion controlled reactions
(Chapter 14), solvation dynamics (Chapter 15), electron transfer in
bulk solvents (Chapter 16) and at electrodes/electrolyte and
metal/molecule/metal junctions (Chapter 17), and several processes
pertaining to molecular spectroscopy in condensed phases (Chapter
18) are the main subjects discussed in this part.

The world-wide sales of polysiloxanes or silicones at the beginning
of this new millennium is approximately $10 billion per year.
Commercial products range from those entirely composed of silicone
to products where the silicone is a low level but key component.
This symposium covered the recent academic and technological
developments behind silicones and silicone-modified materials and
the sessions were well attended of wide interest to both the
academic and industrial communities. The papers from our two highly
successful symposia in this important area were published in the
books Silicones and Silicone-Modified Materials, (Eds. S. J.

Polymeric materials have been and continue to be a focus of
research in the development of materials for energy conversion,
storage and delivery applications (fuel cells, batteries,
photovoltaics, capacitors, etc.). Significant growth in this field
started in the early 1990s and has continued to grow quite
substantially since that time. Polymeric materials now have a
prominent place in energy research.
For polymers, particularly polyelectrolytes, being used in fuel
cell and battery applications, the importance of chain
microstructure, chain dynamics, and nanoscale morphology on the
overall performance characteristics of these materials cannot be
overstated. As further advancements are made in polymer chemistry,
control of nanostructure and characterization, there is a necessity
for organized forums that foster cross-fertilization of knowledge
and ideas between experts in polymer chemistry, chemical
engineering, and polymer physics. This volume is the result of such
a forum.
Most of the chapters in this book are based on a cross-section of
the oral presentations in a symposium on Polymers for Energy
Storage and Delivery held in March of 2011 as part of the 241st ACS
National Meeting & Exposition (Anaheim, CA). The book contains
17 chapters presented in two parts. Part one focuses on polymers
for battery applications and will cover theory and modeling, novel
materials, and materials characterization. Professor Janna Maranas
has provided an excellent review of the current state of
understanding in polyelectrolytes as ion conductors in batteries.
Part two will focus on polymers for fuel cells and will cover novel
materials, transport, and materials characterization with a brief
introduction into the history of polyelectrolytes for fuel cells
and the classes of materials being pursued. Realizing the common
role that nanostructure plays in both battery and fuel cell
applications, Professor Moon Jeong Park and coworkers have also
contributed a chapter demonstrating the role of nanostructured
polyelectrolyte systems in energy storage and delivery. In
addition, the editors are pleased to have a chapter-contributed by
Professor Howard Wang and staff scientists of the NIST Center for
Neutron Research-on the most state-of-art, in-situ neutron methods
for studying lithium ion batteries.
The book gives an overview of the current state-of-the-art
concerning the activation and dissolution of cellulose in a broad
variety of solvents. Research on this topic can lead to new
pathways for the utilization of the most abundant terrestrial
biomolecule and may therefore be the basis for new green strategies
towards advanced materials. Leading scientists in the field show
different conceptions for the solubilization of cellulose. The long
history and groundbreaking developments in the field of polymer
chemistry, which are related to this subject, have lead to timely
alternatives to already established methods. In addition to
discussing attempts for the optimization of known dissolving
procedures, this book also details new solvent systems. New
solvents include inorganic and organic salt melts (ionic liquids),
new aqueous media, multi-component organic solvents and the
dissolution under partial derivatization of the polysaccharide. The
opportunities and the limitations of the solvents are demonstrated,
with a particular emphasis on the stability of the solutions and a
possible recycling of the solvent components.
This book illustrates that the new procedures for cellulose
dissolution can lead to a huge number of unconventional
superstructures of regenerated cellulose material, such as fibers
and polymer layers with a thickness in the nanometer range or
aerogels, i.e. regenerates with a highly porous character and a
large surface. Moreover, cellulose blends can be generated via
solutions. The book also contains chapters that show the amazing
potential of solvents for defined modification reactions on the
cellulose backbone. On one hand, it is possible to synthesize known
cellulose derivatives with new substitution patterns both on the
basis of the repeating unit and along the polymer chain. On the
other hand, completely new derivatives are presented which are
hardly accessible via heterogeneous reactions. Consequently, the
book is intended to give a comprehensive overview of procedures for
dissolution of cellulose. It is of interest for scientists new in
the field but is also a timely summary of trends for experts who
are looking for new approaches for problems related to cellulose
shaping or chemical modification.
Sustainable Polylactide-Based Composites integrates fundamental
knowledge pertaining to manufacturing and characterization of
polymer composites with a thorough and critical overview of the
state-of-the-art in PLA-based composites, including significant
past and recent advances. The book begins with insights into the
basics of polymer composites, with special reference to sustainable
composites, as well as fundamental knowledge related to PLA. This
is followed by chapters on manufacturing methods, morphological
characterization techniques, and the mechanical models used for
polymer composites. A comprehensive overview of the
state-of-the-art in PLA-based sustainable composites of all
extensively used fillers is then presented. After providing
fundamental knowledge related to PLA and polymer composites,
including structure-property-processing relationship, the book
focuses on recent research efforts and key research challenges in
the development of PLA-based composites, as well as lifecycle
assessment and recycling.
There is a growing demand for strategies to address the impact of
polymers and plastics in ecosystems. The principles of green
chemistry offer a good source of such strategies. Ecofriendly
Functional Polymers: An Approach from Application-Targeted Green
Chemistry provides a holistic overview of polymer chemistry,
development, and applications in the context of these
sustainability-driven principles. It encourages researchers to
consider the principles of green chemistry, environmental impacts,
and end-user needs as integral aspects for consideration at the
earliest stages of any design process, and draws together key
aspects of polymer chemistry, organic synthesis, experimental
design, and applications in a single volume. Beginning with an
authoritative guide to fundamental polymer chemistry and its impact
in the current environmental context, the book then discusses a
range of key theoretical and experimental aspects of designing
eco-friendly functional polymers. Applications of ecofriendly
functional polymers across an entire range of fields are discussed,
and a selection of case studies highlights the implementation of
theoretical and experimental information to address a broad
selection of issues.
Molecular Characterization of Polymers presents a range of advanced
and cutting-edge methods for the characterization of polymers at
the molecular level, guiding the reader through theory,
fundamentals, instrumentation, and applications, and supporting the
end goal of efficient material selection and improved material
performance. Each chapter focuses on a specific technique or family
of techniques, including the different areas of chromatography,
field flow fractionation, long chain branching, static and dynamic
light scattering, mass spectrometry, NMR, X-Ray and neutron
scattering, polymer dilute solution viscometry, microscopy, and
vibrational spectroscopy. In each case, in-depth coverage explains
how to successfully implement and utilize the technique. This
practical resource is highly valuable to researchers and advanced
students in polymer science, materials science, and engineering,
and to those from other disciplines and industries who are
unfamiliar with polymer characterization techniques.
Monodispersed Particles, Second Edition, covers all aspects of
monodispersed particles, including inorganic and polymer particles
and their composites. The book consists of four parts:
fundamentals, preparation, analyses, and applications.
Specifically, the fundamental part covers the theoretical insight
into the surface energy of particles and its application to the
formulation of the new theories of nucleation, growth and habit
formation of monodispersed particles. In addition, the theories of
recrystallization and solid-solution formation are introduced.
These fundamental theories are applied to the precise control of
their size, size distribution, shape, internal structure, and
composition, leading to the design of diverse monodispersed
functional particles widely used in basic science and modern
industry. This second edition is fully updated and revised,
detailing new theories and recent progress in the field of
nanoparticles, including advanced nucleation theory, arrested
growth mechanism for monodispersed nanoparticles, and energetics of
habit formation. Additionally, the text covers in-depth insights
into the anisotropic growth of Au and Ag nanoparticles, the
formation mechanisms of polycrystalline Au spheres, iron oxide
nanoparticles in heat-up and hot-injection processes, amorphous
TiO2 spheres in a sol-gel system, anatase TiO2 in a gel-sol system
and their shape control, AgCl nanoparticles in a reverse micelle
system, organic-inorganic hybrid liquid crystals, and extensive
biomedical applications.
Polymeric materials play an essential and ubiquitous role in many
fields including structural and packaging materials, drug
development, tissue engineering, wastewater treatment, pollutant
removal, separation, water purification, smart agriculture, and
even road and building construction. This book contains eleven
comprehensive chapters covering topics from deriving polymers from
natural resources or wastes to developing novel functional
polymeric materials in the form of membranes, hydrogels, foams,
nanocomposites for various environmental applications. This book
also discusses the utilization of waste plastics and the challenges
and progress made in recycling and reusing commercially viable
polymers. Such information is valuable and accelerates
technological progress. Each chapter further gives the current
fabrication methodology, challenges, and future scope of these
materials related to their environmental applications. Thus anyone
working on polymer-based materials will benefit from the
comprehensive knowledge presented in this book on novel polymeric
materials and their various environmental applications.
