This monograph aims to give an overview of recent chemical and technological developments in the area of polymers and co-polymers derived from isobutylene, which have a wide range of (industrial) applications. The scientific basis for presenting the material aEURO" application of the acid-base theory with a view to the fundamental steps of isobutylene polymerization aEURO" is combined with the application of quantum-chemical calculations of catalysts, linked active centers, separate elementary stages of the process, and critical analysis of some experimental data. In addition, a number of problems, such as the macrokinetic description of isobutylene polymerization, description of the balanced scheme of industrial production of isobutylene polymers, and initiation of isobutylene polymerization with the help of immobilized cationic catalysts are discussed. Special attention is given to ecological aspects of synthesis and application of isobutylene polymers. This book will be of value and interest to researchers in the areas of chemistry and physics of high-molecular compounds, as well as engineers and technologists specialized in the area of olefins and polyolefins.

Uniquely beginning with a joke, this monograph addresses scientists specializing in the chemistry and physics of macromolecular compounds as well as engineers and technologists working with olefins and polyolefins. Building on their Isobutylene and its polymers (1985), the authors delve into the properties and latest production methods of isobutylene and polymers derived from it (e.g., butyl rubber), polymerization, and major and new fields of application of polyisobutylenes and the composites derived from them. Credit for publication assistance is given to the Bayer AG (Germany), noted as the main industrial producer of polyisobutylenes.

New fields of science and technology call for new materials with valuable performance characteristics. Long-term resistance to such temperatures can be found only in polymers with chains made up of thermostable fragments. Particularly interesting in this respect are elementorganic polymers with inorganic and organo-inorganic molecular chains. Elementorganic polymers are not only highly thermostable, but also perform well under low temperatures, sunlight, humidity, weather, etc. Thus, these polymers (especially silicones) are widely and effectively used in the electrical, radio, coal, mechanical rubber, aircraft, metallurgical, textile, and other industries. They are of great utility not only in industry, but also in households and in medicine, where their merits can hardly be overestimated. The need to publish this book arose with the scientific and technical developments of the last decade, the reconstruction and technical renovation of existing factories, as well as fundamental changes in some syntheses of elementorganic monomers and polymers. Moreover, nowadays it is essential to train highly skilled chemical engineers with a comprehensive knowledge of current chemistry, of the production technology of elementorganic monomers and polymers, and of their characteristics and applications.

To identify the specific features of the kinetics of oxidation of polymer mixtures, determine the key structural elements, and create a model that can describe the mechanism of thermal oxidation of polymer mixtures, it is necessary to determine the relation between the initial structure of a polymer mixture, structural rearrangements associated with oxidation and the kinetics of the process. The aim of this book is to elucidate the complicated problem concerning the connection between the structure and mechanism of oxidation of heterogeneous and heterophase polymer systems. The material presented in this book concerns the specific features of the kinetics of oxidation and those of the structure of polymer systems. The book deals with an analysis of the key factors that can affect principally the mechanism of thermal oxidation of polymer mixtures, determines the role of the phase morphology, structure of components, and the interface layer (or boundary) in the kinetics of oxidation of heterophase system by an example of mixtures of polyolefines. Along with the kinetics of oxidation of heterophase systems, problems of investigation of their structural parameters in the oxidized state are considered. With this aim, the material presented in the book concerns not only the mechanism of oxidation of polymer mixtures but also homopolymers of diverse morphology and model systems.

Photodegradation and light stabilization are very important aspects of polymer aging. Polymer degradation includes different types of processes: thermodegradation, oxidation, acting of ozone, photodegradation, radiation, hydrolysis, mechanical degradation, and biodegradation. It is very important to know the mechanism of polymer degradation in order to select stabilizers against the degradation. This volume presents the analysis of achievements in the field of photodegradation of polymers. It includes, first of all, data of Russian investigators who have decisively contributed in the development of this field of knowledge (the schools headed by academicians V.V. Korshak, N.M. Emanuel, N.S. Enikolopov, A.A. Berlin, and many others).

This book presents investigation results of thermal transformations in thermoresistant polymers: polysulfones, polyester-imides, aliphatic-aromatic polyimides and polyamides, liquid-crystal aromatic co-polyesters, polyphenylquinoxalines at temperatures of materials and articles processing and operation. An important result of investigations is the determination of thermooxidative degradation regularities for aliphatic-aromatic heterochain polymers and description of the degradation mechanism. The applied aspect of this work is the approach to stabilization of thermoresistant polymers and composite materials derived from them using additives and analysis of the mechanism of high-temperature inhibited oxidation. The book presents results which have been obtained through many years of research until recently, mostly obtained by scientists of G.S. Petrov Research Institute of Polymeric Materials (Moscow, Russia) – one of the leading Institutes in this branch - which have not been available in international scientific publications before.

The monograph is intended for elucidation of the novel trend in chemical physics regarding the polymer non-crystalline phase. It stresses the physical phenomena affecting the kinetics and mechanism of chemical reactions proceeding in the non-crystalline polymer matrix (NCPM). NCPM is depicted in terms of a supramolecular (carcass-micellar) model. The model is thought to reflect heterophase packing of polymeric chains, which co-operate as a molecular-chain sponge. The NCPM model presented is proved for adequate description of principal structure-physical phenomena to elaborate the scheme of structural-kinetic modeling of chemical reactions in bulky polymers. Structure-physical phenomena elucidated in the monograph are: - peculiarities of polymer plasticization and polymer blending with liquids; - structural and thermodynamic aspects of sorption of low molecular species; - properties of ESR (spin) probes and optical (molecular) probes; - features of water absorbed by polymers; - mechanical and thermal effects generated by the molecular-chain sponge; - supramolecular aspects of NCPM chemical physics. This monograph includes the structural-kinetic modeling of complex polymer chemical reactions. It deals with the problem of mechanism and kinetics of free radical chain reactions using thermal and photochemical model reactions of dibenzoyl peroxide with glassy-like polymers (cellulose triacetate, polycarbonate, polystyrene, polyamide PA-548), viscoelastic polymers (atactic polypropylene, polyamide PA-548, polyethylene, polyisobutylene, melted poly(ethylene oxide), and isotactic polypropylene. In all cases, the supramolecular heterophase mechanism of the processes, which was unknown for homogeneous systems, was proved. Furthermore, heterophase mechanisms of photochemical reaction between naphthalene and cellulose triacetate and photolysis of poly(methyl methacrylate) proceeding as a photochain reaction are indicated.
