Synthesis And Properties Of Low And High Molecular Compounds

The main goal of this book is to describe the synthesis and properties of low and high-molecular compounds on the quantitative level. Special attention was given to composition materials based on polymers and dispersed wood, the mechanism of HCL elimination reactions via a four-centre transition state during PVC thermal destruction, swelling of the filled polymer compositions, structure and properties of combined systems based on butadiene-nitrile and ternary ethylene-propylene elastomers, intensification mass transfer processes in fast liquid-phase chemical reactions, the examples of hetero-nanophase kinetic description of photochemical reactions, the nanometric particle-like local structures and their implications in polymer behaviour, fractal physical chemistry of polymer solutions, modification of polycyanurates by polyethers, polyesters and polyurethanes, hybrid and interpenetrating polymer networks. This collection includes articles devoted to production of polymers, polymeric mixtures, composite and filled polymers, questions of expanding lifetime of polymeric articles, biologically active substances, modification of polymers and polymer-analogous transformations, fractal physical chemistry of polymer solutions, the study of structural transformations in polymers and some other questions. Of special attention are also production of pure substances and protection of the environment.

This book covers broad aspects of the chemistry of π-stacked polymers and low-molecular-weight molecules, from synthesis through theory. It is intended for graduate students and researchers in academia and industry and consists of chapters written by renowned scientists who have made significant contributions to this field in the past decade. π-Stacked polymers and low-molecular-weight molecules are expected to replace main-chain conjugated polymers such as polyacetylenes and polythiophenes as organic conducting and energy-transferring substances that are important as materials for photo-electronic applications. π-Stacked polymers and molecules have significant advantages over main-chain conjugated polymers, i.e., high solubility in solvents, large freedom in molecular design, and colorless nature.

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 – application of the acid-base theory with a view to the fundamental steps of isobutylene polymerization – 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.

The demand for organosilicon elastomers used in the production of thermally resistant rubbers and organosilicon polymers for making non-metal composite materials is increasing from year to year.This monograph presents a discussion on the methods used for synthesizing and studying properties of newly designed organosilicon polymers, namely organosil
