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. 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 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. 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.

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.

Advanced composite materials or high performance polymer composites are an unusual class of materials that possess a combination of high strength and modulus and are substantially superior to structural metals and alloys on an equal weight basis. The book provides an overview of the key components that are considered in the design of a composite, of surface chemistry, of analyses/testing, of structure/property relationships with emphasis on compressive strength and damage tolerance. Newly emerging tests, particularly open hole compression tests are expected to provide greater assurance of composite performance. This publication is an "up-to-date" treatment of leading edge areas of composite technology with literature reviewed until recently and includes thermoplastic prepregs/composites and major application areas.

This book includes papers on polymeric materials from renewable resources known as Biorelated Polymers and Plastics', and issues are bound to their utilization and environmental impact in their production, conversions to manufacts and ultimate disposal of post-costume manufacts. Modern industrial developments inspired by the new concepts of sustainability and ecocompatibility require a deeper attention to renewable resources as a new-old source of raw material and feedback. This new trend, occurring not only in industrialized countries but also in emerging countries and countries in transition, thoroughly permeates the polymer and plastic industry, due to the big impact that those materials have on the modern way of life. Plastic waste, specifically that stemming from segments of packaging, containers for solids and liquids and single use items, is attracting much effort from municipality officers, producers and converters, aimed at finding a harmonized solution among the various options available for their appropriate management. In this respect, polymeric materials of natural origin (biopolymers), as well as materials from renewable resources useable for the production of monomeric precursors, or semi-synthetic polymeric materials, constitute a focal point for future industrial development in the production of polymers and plastics. The present book contains much valuable information and scientific hints on a modern approach aimed at designing processes and products with minimal negative environmental impact.

R. W. DYSON There will be few readers of this book who are not aware of the contribution that polymers make to modern life. They are to be seen around the home, at work, in transport and in leisure pursuits. They take many forms which include plastic mouldings and extrusions, plastic film and sheet, plastic laminates (fibreglass and formica), rubber gloves, hoses, tyres and sealing rings, fibres for textiles and carpets and so on, cellular products for cushioning and thermal insulation, adhesives and coating materials such as paints and varnishes. The majority of these polymers are synthetic and are derived from oil products. The most important of these in terms of tonnage used are polymers based upon styrene, vinyl chloride, ethylene, propylene and butadiene among plastics and rubber materials, and nylons, polyethyleneterephthalate and poly acrylonitrile among fibres. The total amount of these polymers used each year runs into millions of tonnes. These polymers are sometimes known as commodity polymers because they are used for everyday artefacts. They are available in many grades and formats to meet a variety of applications and processing techniques. The properties can be adjusted by using additives such as heat and light stabilizers, plasticizers, and reinforcing materials. Often, grades are specially designed and formulated to meet particular requirements and, in a sense, these might be regarded as specialities. Much has been written about these materials elsewhere and they are not the concern of this book.

Polymers are normally thought of as insulators. In the last few years, however, a rapidly advancing and changing field has developed which exploits the ability of certain polymers to conduct charge, in some cases electronically and in others by means of ions. Certain electrochemical processes of major present-day industrial importance depend on the presence of polymeric materials for their efficient operation. The chlor-alkali industry is a prime example. Exciting new power sources, in which polymers replace conventional electrodes and/or electrolytes, are being intensively developed. Re- markable advances in the understanding of electrochemical processes and the development of a range of sophisticated sensors and other devices have been made possible by the use of polymer-coated electrodes. The impact of polymers on the electrochemical field is still in its initial growth phase. The results of a rapidly escalating volume of industrial and academic research are being applied in many contexts, especially in the information technology field. In certain areas, the use of polymers is only just beginning to show its impact. In the next year or so, the use of polymerised Langmuir-Blodgett films as a substitute for conventional E-beam resists in electronics can be anticipated. By the end of the decade, polymerised mono- and multi-layers may be incorporated in very large-scale integrated circuits.

Polymers occur in many different states and their physical properties are strongly correlated with their conformations. The theoretical investigation of the conformational properties of polymers is a difficult task and numerical methods play an important role in this field. This book contains contributions from a workshop on numerical methods for polymeric systems, held at the IMA in May 1996, which brought together chemists, physicists, mathematicians, computer scientists and statisticians with a common interest in numerical methods. The two major approaches used in the field are molecular dynamics and Monte Carlo methods, and the book includes reviews of both approaches as well as applications to particular polymeric systems. The molecular dynamics approach solves the Newtonian equations of motion of the polymer, giving direct information about the polymer dynamics as well as about static properties. The Monte Carlo approaches discussed in this book all involve sampling along a Markov chain defined on the configuration space of the system. An important feature of the book is the treatment of Monte Carlo methods, including umbrella sampling and multiple Markov chain methods, which are useful for strongly interacting systems such as polymers at low temperatures and in compact phases. The book is of interest to workers in polymer statistical mechanics and also to a wider audience interested in numerical methods and their application in polymeric systems.

More than simply an up-to-date review of ionic polymerization, this book presents an in-depth and critical comparison of the anionic and cationic polymerization of vinyl monomers and heterocyclic compounds. These different modes of ionic polymerization are examined with regard to their capacity for producing living polymers. The concept of living polymers is re-examined and redefined in light of current knowledge of ionic polymerization and possible side reactions. Throughout, the authors offer perceptive insights into the basic concepts of polymerization chemistry and polymerization reaction mechanisms. The book begins with a review of ionic and radical polymerizations, the development of ionic polymerization, living and dormant polymers, and polymerizability. It goes on to consider important aspects of the structure and properties of ionic species; initiation and propagation of ionic polymerization; polymerization steps other than initiation or propagation, such as termination, isomerization, transfer, backbiting, and degraduation; and ionic copolymerization. Ionic Polymerization and Living Polymers is a much needed advanced text that will be widely read and referred to by polymer scientists, macromolecular chemists, and materials scientists.

The present book is devoted to a rapidly developing field of science which studies the behavior of viscoelastic materials under the influence of deformation the rheology of polymers. Rheology has long been treated as the theoretical foundation of polymer processing, and from this standpoint it is difficult to overesti mate its importance in practice. Rheology plays an important role in developing our ideas on the nature of viscoelastic behavior in connection with the structural features of polymers and composites based on them. This expands the possibilities of employing rheological methods to characterize a variety of materials and greatly magnifies the interest in this field of research. The rheological properties of polymer systems are studied experimen tally, chiefly under conditions of shear and tensile strains. One explana tion is that many aspects of polymer material processing are associated with the stretching of melts or a combination of shear and tensile strains. In scientific investigations, either periodic or continuous conditions of shear deformation are employed. Each mode provides widespread infor mation. In periodic deformation, most attention is generally given to conditions with low deformation amplitudes that do not alter the structure of the polymer system during an experiment (the region of linear deformation conditions). Here the viscoelastic parameters are generally determined with respect to the frequency. Continuous deforma tion involves considerable strains, and may be attended by significant reversible and irreversible changes in the structure of a polymer."

This book is concerned with the configuration of polymers at the interfacial zone between two other phases or immiscible components. In recent years, developments in technology combined with increased attention from specialists in a wide range of fields have resulted in a considerable increase in our understanding of the behavior of polymers at interfaces. Inevitably these advances have generated a wealth of literature and although there have been numerous reviews, a critical treatment with adequate descriptions of both theory and experiment, including detailed analysis of the two, has been missing. This text hopes to fill this gap, providing a timely and comprehensive account of the field as it stands today. This long needed work will be invaluable to experts as well as newcomers in the broad field of polymers, interfaces and colloids, both in industry and academia. Whilst industrial laboratories involved in this field will find it indispensable, it will be equally important to anyone with an interest in interfacial polymer or colloidal research.
