Organic Additives and Ceramic Processing: With Applications in
Powder Metallurgy, Ink, and Paint describes the major manufacturing
processes, such as slip casting, tape casting, injection molding,
etc. The book covers each subject, including the ceramic processes,
organic chemical structures, polymers, colloid science and others,
starting from fundamental principles, with many literature
references for further reading. After the fundamentals, detailed
case studies from industrial applications are described for the
optimization of solvents, dispersants, binders, plasticizers,
lubricants and some minor additives. A wide range of information is
covered, beginning with fundamental equations for students, and
extending to advanced applications for development workers and
factory problem solvers. Shanefield undertook this ambitious task
only because of the previous lack of resources that address the
growing need for detailed information on organic additives for
ceramics. Suitable for use as a textbook and as a reference source
for working ceramists and chemists who wish to supply the ceramics
industry with additives.
Databook of Curatives and Crosslinkers contains extensive data on
the most important curatives and crosslinkers in use today. Forty
groups of curatives/crosslinkers are included in the book. They
include the following chemical groups of additives: acids,
acrylamides, aldehydes, amides, amidoamines, amines, anhydrides,
aziridines, borates, epoxy-functionalized polymers, carbamides,
carbodiimides, chitosan derivatives, cyanamides, diols, glutarates,
glycols, graphene oxide derivatives, hydantoin glycols, hydrazides,
hydroxides, hydroxyl-containing moieties, imidazoles, isocyanates,
isocyanurates, ketimines, maleimides, melamines, novolacs,
peroxides, peroxyketals, phenols, polyols, salts, silanes,
siloxanes, thiols, titanates, and ziconium derivatives. In total,
416 additives are included in the book.Information on each additive
is divided into five sections: General Information, covering name,
CAS #, active matter, amine nitrogen, chemical class, cure
schedule, and more, Physical Properties, covering odor, color,
density, freezing point, gel time, particle size, thin film set
time, and more, Health and Safety, covering autoignition
temperature, dermal LD50, exposure limits, flash point, and more,
Ecological Properties, covering toxicity to algae, bacteria, and
fish, sewage treatment, and more, and Use and Performance, offering
information on manufacturers, outstanding properties, and more. To
improve navigation throughout the book, four indices have been
generated, as follows. The index of curative names is placed at the
beginning of the book. Indices of the chemical composition of
curatives/crosslinkers, their application for different polymers,
and product applications can be found at the end of this book.

This book deals with the organic chemistry of polymers which find
technological use as adhesives, fibres, paints, plastics and
rubbers. For the most part, only polymers which are of commercial
significance are considered and the primary aim of the book is to
relate theoretical aspects to industrial practice. The book is
mainly intended for use by students in technical institutions and
universities who are specializing in polymer science and by
graduates who require an introduction to this field. Several
excellent books have recently appeared dealing with the physical
chemistry of polymers but the organic chemistry of polymers has not
received so much attention. In recognition of this situation and
because the two aspects of polymer chemistry are often taught
separately, this book deals specifically with organic chemistry and
topics of physical chemistry have been omitted. Also, in this way
the book has been kept to a reasonable size. This is not to say
that integration of the two areas of polymer science is
undesirable; on the contrary, it is of the utmost importance that
the inter-relationship should b~ appreciated. I wish to record my
thanks to my colleagues with whom I have had many helpful
discussions, particularly Mrs S. L. Radchenko. I also thank Miss E.
Friesen for obtaining many books and articles on my behalf and Mr
H. Harms for encouragement and assistance. I am also grateful to
Mrs M. Stevens who skilfully prepared the manuscript. Department of

Silicon in Polymer Synthesis gives the first concise overview of
silicon used for the synthesis and modification of polymers. The
first section gives an introduction to the topic. The subsequent
chapters detail the current status both from the basic research as
well as from the industrial application points of view.
The policy adopted in Volume 1 of this series of including a
relatively small number of topics for detailed review has been
continued here. The techniques selected have received considerable
attention in recent years. F or this reason and because of the
significance of the characterisation data, further coverage of 13C
nuclear magnetic resonance spectroscopy and small angle neutron
scattering is given in the first two chapters. In Chapter I a large
part of the review describes the determination of monomer sequence
distributions and configurational sequences in copolymers formed
from more than one polymerisable monomer. The review on neutron
scattering (Chapter 2) is directed towards the determination of the
chain conformation in semi-crystaIIine polymers, which has provided
important results for the interpretation of chain folding and
morphology in crystaIIisable polymers. Laser Raman spectroscopy has
also been used for morphological studies, and this application
together with a description of the theoretical and experimental
aspects of the technique is given in Chapter 3. X-ray photoelectron
spectroscopy because of its extreme sensitivity to surface
characteristics has provided information on polymeric solids that
could not be obtained by other techniques. The principles and
practice of this ESCA technique, including its use for simple
elemental analysis, structural elucidation and depth profiling, are
described in Chapter 4. The final two chapters are mainly concerned
with the chain conformation of polymers in dilute solution.
Ultrasonic techniques (Chapter 5) show pmmise for observing the
dynamics of conformational changes.
The proceedings of the Twenty-First University Conference on
Ceramic Science held at The Pennsylvania State University,
University Park, PA on July 17, 18 and 19, 1985 are compiled in
this volume "Tailoring Multiphase and Composite Ceramics." This
Conference emphasized the' discussion and analysis of the
properties of multiphase ceramic materials in which the
microstructure is deliberately tailored for specific applications
or properties. Inter nationally recognized authorities presented
keynote and invited lectures on topics dealing with processing and
fabrication of multiphase and com posite electroceramics, fiber
reinforced composites and high temperature multiphase ceramics.
Results of recent research were presented in oral and poster
sessions by leading researchers from several countries. This
collection of papers represents the state of the art in our
understand ing of the processing-structure-property
interrelationships for these materials which possess unique and
useful electrical, magnetic, optical, mechanical and thermal
properties as a result of their multiphase nature. We are grateful
for the financial support of the National Science Foundation, the
Office of Naval Research, the Air Force Office of Scien tific
Research, and the Defense Advanced Research Projects Agency for
this conference. We gratefully acknowledge Prof. Robert Davis'
leader ship role in steering and expanding this university
conference series on ceramic science. We thank Ron Avillion and
Linda Rose for their expert assistance in planning and coordinating
the meeting. Thanks are due to Ms. Marian Reed, Ms. Judy Bell and

Holographic Interferometry provides a valuable and up-to-date
source of information in the rapidly expanding field. The eight
specialists` contributions cover the principles and methods
currently in use. The scope of the book has been limited to the
study of opaque object and ample space has been devoted to a
comprehensive treatment of the phenomena of fringe formation, with
a particular emphasis on the quantitative evaluation of the
holographic interference fringe patterns. The emergence of
computer-aided fringe analysis and phase-shifting techniques have
simplified considerably the quantative real-time measurements of
object shapes and deformations. The last two chapters provide a
reasonably detailedoverview of full-field holographic methods for
the measurement of shapes, displacements, dervatives, difference
displacements and vibrations.

The second edition of this textbook is identical with its fourth
German edi tion and it thus has the same goals: precise definition
of basic phenomena, a broad survey of the whole field, integrated
representation of chemistry, physics, and technology, and a
balanced treatment of facts and comprehen sion. The book thus
intends to bridge the gap between the often oversimpli fied
introductory textbooks and the highly specialized texts and
monographs that cover only parts of macromolecular science. The
text intends to survey the whole field of macromolecular science.
Its organization results from the following considerations. The
chemical structure of macromolecular compounds should be inde
pendent of the method of synthesis, at least in the ideal case.
Part I is thus concerned with the chemical and physical structure
of polymers. Properties depend on structure. Solution properties
are thus discussed in Part 11, solid state properties in Part Ill.
There are other reasons for dis cussing properties before
synthesis: For example, it is difficult to understand equilibrium
polymerization without knowledge of solution thermodynamics, the
gel effect without knowledge of the glass transition temperature,
etc. Part IV treats the principles of macromolecular syntheses and
reactions."
This second edition has been designed to monitor the progress in
develop ment over the past few years and to build on the
information given in the first edition. It has been extensively
revised and updated. My thanks go to all who have contributed to
this work. D.F.W. May 1996 Preface to the first edition This book
is the result of a group of development scientists feeling that
there was an urgent need for a reference work that would assist
chemists in understanding the science involved in the development
of new products. The approach is to inform in a way that allows and
encourages the reader to develop his or her own creativity in
working with marketing colleagues on the introduction of new
products. Organised on a product category basis, emphasis is placed
on formulation, selection of raw materials, and the technology of
producing the products discussed. Performance considerations,
safety, product liability and all aspects of quality are covered.
Regulations governing the production and sale of cosmetic products
internationally are described, and sources for updated information
provided. Throughout the book, reference is made to consumer
pressure and environmental issues-concerns which the development
scientist and his or her marketing counterpart ignore at their own,
and their employer's peril. In recent years, many cosmetic
fragrances and toiletry products have been converted from aerosols
to mechanically press uri sed products or sprays, and these are
described along with foam products such as hair conditioning
mousses."

The chemistry of transition metal carbyne complexes has become a
highly attractive field during the past twenty years. In recent
years its application to aspects of catalysis and metathesis has
gained considerable interest from inorganic as well as organic
chemists. In addition, organic synthesis by means of metal carbon
multiple bond reagents offers the most sophisticated technology
currently available. In consideration of these developments some of
Professor E. O. Fischer's former coworkers and colleagues felt
obliged to orga nize this NATO Advanced Research Workshop on
Transition Metal Carbyne Complexes in the Bavarian Alps. They have
been encouraged by the fact that most of the distinguished
scientists in the field of metal-carbon multiple bond chemistry had
finally agreed to participate and to present stimulating lectures.
The organizers of the workshop are deeply grateful to the
Scientific Affairs Division of the NATO for the generous financial
support of the meeting in Wildbad Kreuth and for the preparation of
this book. They also feel indebted to acknowledge the generous
support from Wacker-Chemie, BASF, Peroxid-Chemie, Hoechst and
Bayer. Finally they thank the staff of the Hanns-Seidel-Stiftung in
Wildbad Kreuth for providing a pleasant and stimu lating atmosphere
during the meeting."
This volume is comprised of most of the papers presented at a
symposium held in Miami Beach during the national meeting of the
American Chemical Society in September, 1978. In a sense, it is a
sequel to the first ACS symposium held on this topic and published
under the title "Polymer Colloids" in 1971 by Plenum Press. That
volume contained 12 papers, whereas "Polymer Colloids II" contains
33, an indication of the magnitude of the growth of the field in
less than a decade. Increased sophistication probably best
characterizes the changes which have taken place, especially in the
realm of instru mentation. Ten years ago techniques such as
quasielastic light scattering, X-ray photoelectron spectroscopy
(XPS - also known as ESCA), ion scattering spectroscopy (ISS),
ultrasonic absorption spectroscopy and hydrodynamic exclusion
chromatography (REC) were unavailable to the polymer colloid
chemist. Recent advances in all of these methods are described in
this volume. Although the book deals primarily with "synthetic
latexes" or "emulsion polymers" as colloids, there are a number of
papers which deal with their synthesis: particle nucleation in
emulsion polymer ization, the synthesis of emulsifier-free polymer
colloids using novel reagents, molecular weight distributions
derived from the kinetics of emulsion polymerization, and
anionically polymerized non-aqueous polymer colloids. The kinetics
and thermodynamics of the swelling of latex particles by monomers
is also dealt with here."
The past decade has witnessed a vigorous growth in activities
toward the development of a variety of biomedical devices ranging
from the simple A-V shunt to the complex artificial heart. Re
search and development teams have been created comprising engi
neers, material scientists and clinicians and, perhaps for the
first time, such groups are collaboratively bringing their respec
tive talents to bear on problems associated with defects in the
human organism. These collaborations have resulted in a prolifera
tion of new information and a rapid and continuing redefinition of
the frontiers of progress. It was to keep pace with these changes,
and provide an updated view of the state of the art that this
meeting was conceived. The present volume marks the publication of
the proceedings of the Johnson & Johnson Symposium held in
Morristown, New Jersey, on July 11 and 12, 1974. It surveys the
applications of polymers to medical and surgical problems and
contains discus sions on the biocompatibility of polymers, polymers
as biomate rials, and the use of polymers in prosthetic devices and
drug re lease systems. In addition, the Symposium offers recent
perspec tives on the critical problems of the material-tissue
interface, the design criteria for silicone-based systems, and the
varied use of polymers in artificial hearts, kidneys, eyes and
lungs."
The last decade or so has seen a dramatic increase in the amount of
detailed structural information available from a range of
experimental techniques. Exciting new techniques such as atomic
force microscopy have become widely available, while the potential
of established methods like X-ray diffraction and electron
microscopy has been greatly enhanced by powerful new sources and
analytical methods. Progress in computing has also had a widespread
impact: in areas such as neutron scattering, large data sets can
now be manipulated more readily. The software supplied with
commercial instruments generally provides more sophisti cated
analytical facilities, while time-resolved X-ray studies rely on
rapid data handling capabilities. The polymer scientist is faced
with an expanding array of experimental tools for addressing both
fundamental science and industrial problems. This work reviews some
recent developments in structural techniques, with the aim of
presenting the current 'state of the art' in a selection of areas."
New technologies constantly generate new demands for exotic
materials to be used in severe environments. The rapid developments
of aerospace industries during the last two decades have required
new materials to survive extreme high and low temperatures and
various radiations. The exploration of new energy sources, e.g.,
solar and geothermal, has led us to develop new solar collectors
and geothermal devices. Even the search for new oils has demanded
that we study the corrosive environment of oil fields. In the
telecommunication industries, optical fibers have been adopted
broadly to replace metallic conductors. However, none of the
optical fibers can survive abrasion or corrosion without the
application of a coating material. For microelectronics, protection
in terms of coatings and encapsulants is deemed necessary to
prevent corrosion. One of the major causes of corrosion has been
shown to be water which appears to be abundant in our earthly
environments. Water can attack the bulk adhesive (or sealant), the
interface, or the adherend. Water can also cause delamination of
coating film, and it is definitely the major ingredient in causing
cathodic or anodic corrosion. Thus, water becomes the major
obstacle in solving durability problems of various materials in
harsh environments.
Targeting of drugs via carrier systems to sites in the body in need
of pharmacologic intervention is a rapidly growing area of research
in the treatment or prevention of disease. It has evolved from the
need to preferentially deliver drugs, enzymes, vitamins, hormones,
antigens, etc. to target cells and organs so as to avoid toxicity,
waste of drugs through premature secretion or inactivation and at
the same time render treatment more convenient and cost-effective.
A wide assortment of naturally occ urring or semi-synthetic drug
carriers (e. g. antibodies, glycoproteins, lectins, peptide
hormones, cells and liposomes), their inter action with relevant
receptors and mediation of optimal pharmacological action were
discussed in the two previous NATO Advanced Studies Institutes
(ASI) of this series, "Targeting of Drugs" and "Receptor-Mediated
Targeting of Drugs," the proceedings of wh ich were published by
Plenum in 1982 and 1984 respectively. This book contains the
proceedings of the 3rd NATO ASI "Targeting of Drugs with Synthetic
Systems" held as be fore at Cape Sounion, Greece during 24 June-5
July 1985. It deals mostly with man-made carriers such as a variety
of polymers, matrices, liposomes and other colloidal micro
particles. The twenty chapters discuss the interaction of such
carriers with the biological milieu, approaches to bypass the
reticuloendothelial system (or, when needed, take advantage of its
interception of carriers to optimally deliver drugs to phagocytes)
and ways to improve delivery to specific cells, often with the help
of carrier-linked ligands."
