A handbook on polyolefins. This second edition includes new
material on the structure, morphology and properties of polyolefin
(PO) synthesis. It focuses on synthetic advances, the use of
additives, special coverage of PO blends, composites and fibres,
and surface treatments. It also addresses the problem of
interfacial and superficial phenomena.
Environmentally Degradable Materials (EDPs) should replace
petroleum-based plastics where recycling is not viable for logistic
or labor cost reason. This book discusses the general background of
obtaining such systems, compatibilization methodologies, control of
the rate of degradation and final products after degradation, life
time assessment, toxicological aspects, applications and market
aspects. This book is a complete guide to the subject of
biodegradable materials based on multi-component polymeric systems,
mainly such as hydrogels, and interpenetrating polymeric networks.

Polymeric Nanomaterials in Nanotherapeutics describes how polymeric
nanosensors and nanorobotics are used for biomedical
instrumentation, surgery, diagnosis and targeted drug delivery for
cancer, pharmacokinetics, monitoring of diabetes and healthcare.
Key areas of coverage include drug administration and formulations
for targeted delivery and release of active agents (drug molecules)
to non-healthy tissues and cells. The book demonstrates how these
are applied to dental work, wound healing, cancer, cardiovascular
diseases, neurodegenerative disorders, infectious diseases, chronic
inflammatory diseases, metabolic diseases, and more. Methods of
administration discussed include oral, dental, topical and
transdermal, pulmonary and nasal, ocular, vaginal, and brain drug
delivery and targeting. Drug delivery topics treated in several
subchapters includes materials for active targeting and cases study
of polymeric nanomaterials in clinical trials. The toxicity and
regulatory status of therapeutic polymeric nanomaterials are also
examined. The book gives a broad perspective on the topic for
researchers, postgraduate students and professionals in the
biomaterials, biotechnology, and biomedical fields.
Polymer/clay nanocomposites are a new class of reinforced polymer
materials containing low quantities of nanometric-sized clay
particles which impart them better mechanical, thermal, electrical,
barrier properties, chemical resistance, etc., making them valuable
materials in many industrial applications such as; coatings,
automotive, packaging, construction, and electronics, etc. They
have great potential of increasing the fields of use which
indicates them as likely to be involved in many various aspects of
our lives in the near future. This book explains the preparation of
polymer/clay nanocomposites via emulsion polymerization system and
reveals a detailed study on the latex stability which arises as a
challenge during nanocomposite latex preparations. The improvements
of mechanical and thermal properties of the nanocomposite films as
well as the rheological aspects of latexes which have crucial
importance for coating applications are discussed. The book also
includes a case application of the synthesized nanocomposite
latexes as binders in leather finishing and the performance of the
nanocomposite coatings is reported as well.
The book focused on the practical aspects of reactive
compatibilization-cum-impact modification of complex systems
containing both virgin polymers and/or their mixed plastic waste.
This issue is critical for waste management as the mechanical
recycling is the most viable method, it demands sorting of plastic
waste for homogeneous streams- a costly process. Possibility of
avoiding this stage by means of reactive compatibilization would
make reprocessing much simpler and cheaper in parallel with
providing high quality of the end products based on recyclates. The
findings on a combined method of compatibilization and impact
modification obtained by the authors for virgin polymers like
polyolefins (LDPE and PP) and polyamide 6 (PA6) have been also
verified for the blends of virgin/recycled polymers. LDPE and PP
have been melt functionalized with three polar monomers and further
used as reactive compatibilizers, while ethylene-propylene-diene
(EPDM) termonomer has been used as an impact modifier. Complex
investigations and characterization of advanced multicomponent
polymeric systems carried out in this book provided several
innovative results, both with scientific and practical value.
This collection of texts written by well-recognised specialists was
constituted having in view these important directions of actual
research. Sustainable economical growth requires safe resources of
raw materials for the industrial production. Today's most
frequently used industrial raw material, petroleum, is neither
sustainable, because limited, nor environmentally friendly. While
the economy of energy can be based on various alter-native raw
materials, such as wind, sun, water, biomass, as well as nuclear
fission and fusion, the economy of substances is fundamentally
depending on biomass, in particular biomass of plants. In the last
decades because of the crude oil and other natural resources
crisis, a new alternative has been proposed consisting in
utilisation of renewable natural resources as feedstock and fuel,
among which the biomass is the most promising.
Polymers are substances containing a large number of structural
units joined by the same type of linkage. These substances often
form into a chain-like structure. Starch, cellulose, and rubber all
possess polymeric properties. Today, the polymer industry has grown
to be larger than the aluminium, copper and steel industries
combined. Polymers already have a range of applications that far
exceeds that of any other class of material available to man.
Current applications extend from adhesives, coatings, foams, and
packaging materials to textile and industrial fibres, elastomers,
and structural plastics. Polymers are also used for most
composites, electronic devices, biomedical devices, optical
devices, and precursors for many newly developed high-tech
ceramics. This book presents leading-edge research in this
rapidly-changing and evolving field.
