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.

Chemistry and chemical engineering have changed significantly in the last decade. They have broadened their scopeâ€"into biology, nanotechnology, materials science, computation, and advanced methods of process systems engineering and controlâ€"so much that the programs in most chemistry and chemical engineering departments now barely resemble the classical notion of chemistry. Beyond the Molecular Frontier brings together research, discovery, and invention across the entire spectrum of the chemical sciencesâ€"from fundamental, molecular-level chemistry to large-scale chemical processing technology. This reflects the way the field has evolved, the synergy at universities between research and education in chemistry and chemical engineering, and the way chemists and chemical engineers work together in industry. The astonishing developments in science and engineering during the 20th century have made it possible to dream of new goals that might previously have been considered unthinkable. This book identifies the key opportunities and challenges for the chemical sciences, from basic research to societal needs and from terrorism defense to environmental protection, and it looks at the ways in which chemists and chemical engineers can work together to contribute to an improved future.

Using fractal analysis, irreversible aggregation models, synergetics, and percolation theory, this book describes the main reactions of high-molecular substances. It is the first to give the structural and physical grounds of polymers synthesis and curing based on fractal analysis. It provides a single equation for describing the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium.

Of the thousands of novel compounds that a drug discovery project team invents and that bind to the therapeutic target, typically only a fraction of these have sufficient ADME/Tox properties to become a drug product. Understanding ADME/Tox is critical for all drug researchers, owing to its increasing importance in advancing high quality candidates to clinical studies and the processes of drug discovery. If the properties are weak, the candidate will have a high risk of failure or be less desirable as a drug product. This book is a tool and resource for scientists engaged in, or preparing for, the selection and optimization process. The authors describe how properties affect in vivo pharmacological activity and impact in vitro assays. Individual drug-like properties are discussed from a practical point of view, such as solubility, permeability and metabolic stability, with regard to fundamental understanding, applications of property data in drug discovery and examples of structural modifications that have achieved improved property performance. The authors also review various methods for the screening (high throughput), diagnosis (medium throughput) and in-depth (low throughput) analysis of drug properties. Serves as an essential working handbook aimed at scientists and students in medicinal chemistry Provides practical, step-by-step guidance on property fundamentals, effects, structure-property relationships, and structure modification strategies Discusses improvements in pharmacokinetics from a practical chemist's standpoint
