Provides a thorough description of all major plastics processing methods, including theory and practice.

MALDI-TOF mass spectrometry is one of the latest and most fascinating new developments in the analysis of organic compounds. Originally developed for the analysis of biomolecules, it has developed into one of the most powerful techniques for the characterization of synthetic polymers. This book describes the fundamentals of the MALDI process and the technical features of MALDI-TOF instrumentation. It reviews the application of MALDI-TOF for identification, chemical and molar mass analysis of synthetic polymers. With many examples, this monograph examines in detail experimental protocols for the determination of endgroups, the analysis of copolymers and additives, and the coupling of liquid chromatography and MALDI-TOF.

Since publication of the first edition of this Handbook, the usage of thenno plastic elastomers (TPEs) has doubled, with a compounded annual growth rate of approximately 9 percent. This second edition summarizes and documents the technological and commercial progress that has given rise to this phenomenal rate of growth. Over the past decade, numerous suppliers and users of ther moplastic elastomers have entered the field, and some have retired from it, a process that almost certainly will continue. This Handbook is intended to serve the broad spectrum of professionals ac tively engaged in the field of thennoplastic elastomers, which has seen a growth rate four to six times that of the rubber and plastics industries. As TPEs embrace both rubber and plastics technology, this book will be useful to rubber and plastics technologists with a broad variety of specific interests. This edition emphasizes commercial practice and practical application rather than research activity. Technology and innovation are stressed, with polymer science functioning as a basis for understanding and communication. We have focused on those TPEs that we consider to be of significant commercial impor tance-the ones now used in the fabrication of useful articles, or which probably will be so used in the foreseeable future."

The rapidly-developing field of confined polymers is reviewed in this volume. Special emphasis is given to polymer aspects of this interdisciplinary problem. Taken together, the contributions offer ample evidence of how the field of polymer science continues to evolve with the passage of time. The topics revolve around the tendency of surfaces to impede chain relaxation and to stimulate new sorts of chain organization. These have been implicated in a variety of spectacular phenomena. Here is a listing of authors and affiliations: K. Binder (Johannes Gutenberg-Universit t Mainz, Germany); P.-G. de Gennes (College de France, France); E.P. Giannelis, R. Krishnamoorti, and E. Manias (Cornell University and University of Houston, USA); G.S. Grest (Exxon Research and Engineering Co., USA); L. Leger, E. Raphael, and H. Hervet (College de France, France); S.-Q.

Biopolymers from Renewable Resources is a compilation of information on the diverse and useful polymers derived from agricultural, animal, and microbial sources. The volume provides insight into the diversity of polymers obtained directly from, or derived from, renewable resources. The beneficial aspects of utilizing polymers from renewable resources, when considering synthesis, pro cessing, disposal, biodegradability, and overall material life-cycle issues, suggests that this will continue to be an important and growing area of interest. The individual chapters provide information on synthesis, processing and properties for a variety of polyamides, polysaccharides, polyesters and polyphenols. The reader will have a single volume that provides a resource from which to gain initial insights into this diverse field and from which key references and contacts can be drawn. Aspects of biology, biotechnology, polymer synthesis, polymer processing and engineering, mechanical properties and biophysics are addressed to varying degrees for the specific biopolymers. The volume can be used as a reference book or as a teaching text. At the more practical level, the range of important materials derived from renewable resources is both extensive and impressive. Gels, additives, fibers, coatings and films are generated from a variety of the biopolymers reviewed in this volume. These polymers are used in commodity materials in our everyday lives, as well as in specialty products."

In recent years various industries have demanded not only greater use of polymeric materials but also the development of polymeric materials with specific properties. Major users include the automotive and transport industries, electrical and electronics industries, and the packaging industry. Following the success of "Speciality Polymers", Dr Dyson's book provides an overview of the main types of polymeric materials used in engineering, and discusses their applications - both practical and potential.

The two volumes 165 and 166 Polyelectrolytes with Defined Molecular Architecture summarize recent progress in the field. The subjects comprise novel polyelectrolyte architectures including planar, cylindrical and spherical polyelectrolyte brushes as well as micelle, complex and membrane formation. Some solution properties such as conformation of flexible polyions, osmotic coefficients and electrophoretic properties are addressed along with recent progress in analytical theory and simulation.

Because of the many important new developments in other branches of science, some scientists fail to recognize that the volume of polyolefins produced annually is greater than that of all metals. Hence, the American Chemical Society s"ponsored symposia on the History of Polyolefins at its national meeting at Miami Beach in the Spring of 1985 and a Macromolecular Secretariat on Advances in Polyolefins at its national meeting in Chicago in the fall of that year. The books on the proceedings of these landmark symposia and another book entitled "The Chain Straighteners" by Dr. F. M. McMillan will provide the scientist with background information which is essential for re- searchers in this important phase of polymer science. The presentations at these international symposia and the publica- tions of the reports presented, would not be possible without the dedicated efforts of our assistant editors and publisher. The list of contributors to ADVANCES IN POLYOLEFINS includes most of the leaders in this field, such as Dr. Mark, Mandelkern, Bruzzone, Hsieh, Kaneda, Chien, Tait, Karol, Kaminisky, Scott, Cook, Mirabella, Samuels, Kanamoto and Vigo. These reports covered many phases of polyolefin science and technol- ogy, ranging from elastomers, single crystals, film and fibers to char- acterizations by modern instrumentation and many new innovations in catalysis which have brought about a revolution in polyolefin production.

This book is the definitive reference on phase-transfer catalysis (PTC), written by the three foremost industrial and academic PTC experts in the world. Phase-Transfer Catalysis, the first practical guide to performing PTC in industry, includes key information and analyses found in no other publication. It will be a valuable resource for synthetic organic chemists, polymer chemists, process chemists, developmental chemists, and chemical engineers in academia and industry. Organic process chemists seeking greater process flexibility, reduced manufacturing costs and pollution, and easier compliance with environmental regulations will find it an indispensable reference. The book provides a thorough introduction to the fundamentals of PTC as a synthetic organic chemistry technique, including reaction mechanisms, selectivity, rates, and kinetics. It gives specific guidelines on how to optimize catalyst, solvent, base, hydration, and more, based on reaction characteristics. The section on applications includes nucleophilic displacement reactions, oxidation and reduction reactions, and such special topics as insoluble PTC (triphase catalysis), polymerization, chiral catalysis, applications in environmental and analytical chemistry, and transition metal co-catalyzed PTC. Throughout the book, PTC applications in key industries are discussed - including organic chemicals, polymers, pharmaceuticals, agrichemicals, monomers, petrochemicals, flavors and fragrances, additives, dyes, and specialty chemicals.

Written by an international team of authors with a strong emphasis on the underlying chemistry, this book forms a timely, concise, and accessible evaluation of the fundamentals of polymer network formation, structure, and properties, and how these three aspects are interrelated.

Chemical modification of polymers by reactive modifiers is no longer an academic curiosity but a commercial reality that has delivered a diverse range of speciality materials for niche markets: reactively grafted styrenic alloys, maleated polyolefins, super-tough nylons, silane modified and moisture-cured polyolefins, and thermoplastic elastomers, are but few exam ples of commercial successes. Although the approach of reactive modification of polymers has been largely achieved either in solution or in the solid state (through in situ reactions in polymer melts), it is the latter route that has attracted most attention in the last two decades owing to its flexibility and cost-effective ness. This route, referred to as reactive processing, focuses on the use of suitable reactive modifier(s) and the adoption of conventional polymer processing machinery, an extruder or a mixer, as a chemical reactor, to perform in situ targeted reactions for chemical modification of preformed polymers. This relatively simple, though scientifically highly challenging, approach to reactive modification offers unique opportunities in exploiting various reactive modifiers for the purpose of altering and transforming in a controlled manner the properties of preformed commercial polymers into new/speciality materials with tailor-made properties and custom-designed performance for target applications. Such an economically attractive route constitutes a radical diversion away from the traditional practices of manufacturing new polymers from monomers which involves massive in vestments in sophisticated technologies and chemical plants."

The fluorine atom, by virtue of its electronegativity, size, and bond strength with carbon, can be used to create compounds with remarkable properties. Small molecules containing fluorine have many positive impacts on everyday life of which blood substitutes, pharmaceuticals, and surface modifiers are only a few examples. Fluoropolymers, too, while traditionally associated with extreme high performance applications have found their way into our homes, our clothing, and even our language. A recent American president was often likened to the tribology of PTFE. Since the serendipitous discovery of Teflon at the DuPont Jackson Laboratory in 1938, fluoropolymers have grown steadily in technological and marketplace importance. New synthetic fluorine chemistry, new processes, and new apprecia tion of the mechanisms by which fluorine imparts exceptional properties all contribute to accelerating growth in fluoropolymers. There are many stories of harrowing close calls in the fluorine chemistry lab, especially from the early years, and synthetic challenges at times remain daunting. But, fortunately, modem techniques and facilities have enabled significant strides toward taming both the hazards and synthetic uncertainties, In contrast to past environmental problems associated with fluorocarbon refrigerants, the exceptional properties of fluorine in polymers have great environmental value. Some fluoropolymers are enabling green technologies such as hydrogen fuel cells for automobiles and oxygen selective membranes for cleaner diesel combustion.

During the past decade, the field of polymer degradation and stabilization has become a subject of central importance in polymer science and technology. This book provides a fundamental source of information designed for those with only a basic understanding of the background of the field.

This paper combines data on production, on processing and formulating, on application, on the waste stream and on the possibilities for recycling polyvinyl chloride insofar as such data has relevance for an assessment of environmental impact. It is intended to help place the PVC debate on a factually well-founded basis. The paper describes many, but not all facets of the environmental effects of a common plastic. This book is based on work carried out at the Fraunhofer Institute for Systems Technology and Innovations Research and particularly on a report drawn up on the order of the Research Centre Julich (Gaensslen, H. , Sordo, M. , TOtsch, W. : Production, Processing and Recycling of PVC. Order Number 011/41072711/930, April 1989). We would like to express our thanks to Dr. Kollmann of KFA Julich for placement of this order. This book would not have come into being but for the assistance given by many colleagues. Magdalena Sordo carried out valuable preliminary work which forms the basis of many parts of the book. We would like to thank the following as representatives of our other colleagues: Eberhard BOhm for proof reading, Gunther Heger for the data base researches and Joachim Waibel for producing the illustrations. The book has been translated by H. P. Kaufmann, Technical Translations, Marketing & Advisory Services, London. We are especially grateful to Harold M. Clayton and his colleagues at Hydro Polymers Ltd for proof-reading the English manuscript. vii Contents Preface 1.

The fluorine atom, by virtue of its electronegativity, size, and bond strength with carbon, can be used to create compounds with remarkable properties. Small molecules containing fluorine have many positive impacts on everyday life of which blood substitutes, pharmaceuticals, and surface modifiers are only a few examples. Fluoropolymers, too, while traditionally associated with extreme hi- performance applications have found their way into our homes, our clothing, and even our language. A recent American president was often likened to the tribology of PTFE.

New synthetic fluorine chemistry, new processes, and new apprec- tion of the mechanisms by which fluorine imparts exceptional properties all contribute to accelerating growth in fluoropolymers. There are many stories of harrowing close calls in the fluorine chemistry lab, especially from the early years, and synthetic challenges at times remain daunting. But, fortunately, modern techniques and facilities have enabled significant strides toward taming both the hazards and synthetic uncertainties.

Polymeric materials are widely used during nearly all stages of the manufacturing process of electronics products and this book is intended to give an introductory overview of the chemistry, properties and uses of some of the more important classes of materials likely to be encountered in these applications. It is intended to serve primarily as an introduction to the use of polymers and plastics in the processing and manufacture of electronic and electrical components and assemblies. With no in-depth knowledge of polymers assumed, the book is ideal for engineers and researchers working in areas where electronics and polymer technology overlap. There are also numerous references for those wishing to delve deeper. The first edition of this book was published in 1985 and since then there has been an unbelievable change and growth in the electronics industry. Much of this has been made possible by the continued development of new and improved polymeric materials. In some areas the polymers used have changed markedly whereas in others there have been continued improvements to the same basic materials. Consequently, this second edition includes new chapters detailing the materials which have emerged more recently. Chapters covering the same topics as the original version have been extensively rewritten and updated, often with the assistance of current international experts. In the last few years much work has been carried out on the development and use of special polymers that have important properties in addition to those normally associated with conventional polymers. This edition therefore includes a chapter that introduces one particular group of materials exhibiting these special properties, the ferroelectric polymers. The book also includes new chapters on high temperature thermoplastics, or engineering plastics as they are sometimes known, and their use in so-called moulded interconnect devices, where the polymer is used to provide a much wider range of functions than has been possible using a more conventional approach. This new edition also has a wider international coverage with chapters by experts based in Belgium, Holland, Switzerland, Germany, England and the United States of America.

Explains the correlation between the physical properties and structure of polymer gels This book elucidates in detail the physics of polymer gels and reviews their unique properties that make them attractive for innumerable applications. Geared towards experienced researchers and entrants to the field, it covers rubber elasticity, swelling and shrinking, deformation and fracture of as well as mass transport in polymer gels, enabling the readers to purposefully design polymer gels fit for specific purposes. Divided into two parts, Physics of Polymer Gels starts by explaining the statistical mechanics and scaling of a polymer chains, and that of polymer solutions. It then introduces the structure of polymer gels and explains the rubber elasticity, which predicts the solid-like nature of polymer gels. Next, it describes swelling/deswelling, which can be understood by combining the rubber elasticity and the osmotic pressure of a polymer solution. Large deformation and fracture, and the diffusion of substances in polymer gels, which are essential for practical applications, are also introduced. The last half of the book contains the authors' experimental results using Tetra-PEG gels and provides readers with the opportunity to examine and compare it with the first half in order to understand how to utilize the models to experiments. This title: * Is the first book dedicated to the physics of polymer gels * Describes in detail the properties of polymer gels and their underlying physics, facilitating the development of novel, polymer gel-based applications * Serves as a reference for all relevant polymer gel properties and their underlying physics * Provides a unified treatment of the subject, explaining the physical properties of polymer gels within a common nomenclature framework Physics of Polymer Gels is a must-have book for experienced researchers, such as polymer chemists, materials scientists, organic chemists, physical chemists, and solid-state physicists, as well as for newcomers to the field.

The current book describes the chemical and physical behaviour of polymers and biopolymers that form highly associating structures in equilibrium solution. It summons the established results known of polymer complexes in solution, taking into account also the recent developments in biotechnology concerning this topic, in technological applications of polymer-protein interactions, in fluorescence and scattering techniques for the study of intra- and interpolymer association and in the study of ionomers in solution. The book covers the whole range from synthesis and fundamental aspects to applications and technology of associated polymers.

Since the publication of the first edition of The Physics of Glassy Polymers there have been substantial developments in both the theory and application of polymer physics, and many new materials have been introduced. Furthermore, in this large and growing field of knowledge, glassy polymers are of particular interest because of their homogeneous structure, which is fundamentally simpler than that of crystalline or reinforced materials. This new edition covers all these developments, including the emergence of the polymer molecule with its multiplicity of structure and conformations as the major factor controlling the properties of glassy polymers, using the combined knowledge of a distinguished team of contributors. With an introductory chapter covering the established science in the subject are and summarising concepts assumed in the later chapters, this fully revised and updated second edition is an essential work of reference for those involved in the field.

Cold-plasma modification of polymers and deposition of thin polymer fIlms is a branch of science characterised by an increasing popularity in the last few years for the targe number of new industrial processes which have been realised by its application. Most plasma scientists can attest this through their everyday experience: many technologists, independently of the size of their company address demands for new products in e. g. electronics, automotive components, optics, food and pharmaceutical packaging, biomedical and surgical equipments, etc. The unique common need of this variety of applications is that the products feature "surfaces" with tailored and unusual properties, which enable their use where otherwise would be impossible to conventional materials. Plasma produced-, or plasma modified-polymers can, in fact, be considered an entirely novel class of materials with tuneable properties showing e. g. chemical inertness or enhanced reactivity, hardness, variable refractive index, hydro-phobicity and -philicity , adhesivity, dyebility, blood compatibility, bacterial infection resistance, etc. The NATO-ASI course on PLASMA TREATMENT AND DEPOSmON OF POLYMERS, held May 19-June 2, 1996, in Acquafredda di Maratea, ltaly, has been designed with an effort to balance not only industrial applications, fundamental bases of plasma physics and chemistry, and diagnostics, but also different international schools of plasma processes with their different or controversial approaches.
