Macromolecular Solutions: Solvent-Property Relationships in Polymers is a collection of papers presented at a symposium on Macromolecular Solutions, held New York City on August 23-28, 1981, sponsored by the American Chemical Society at its 182nd national meeting. This book is composed of 19 chapters and begins with discussions on the concept, application, and analysis of solubility parameters of polymers. The succeeding chapters deal with the role of solubility parameters in polymer coating design and stress cracking of nylon. Considerable chapters are devoted to the preparation, properties, reactions, and analysis of various polymers and copolymers. These topics are followed by surveys of the polymer-surfactant interaction effect on polymer solution properties and the effects of methanol-gasoline mixtures on elastomers. The final chapters describe the residual solvent content effect on dissolution kinetics of polymers; the application of excimer fluorescence to measure polymer-solvent interactions; and a general procedure for the calculation of thermodynamic properties of polymer solutions. This book will be of great value to polymer chemists, manufacturers, and researchers.

Conformation is statistical property of the macromolecules consisting of a number of N structural units, links, position of which in a space one relatively to other is not inflexibly fixed by chemical bonds and assumes the possible random configurations. The number of possible configurations at N ” 1 is so great that permits to use the statistical methods at their analysis. That is why the conformation is a result of statistical averaging on all possible configurations of the macromolecule. It was for a long time notified and confirmed by computer modelling that the conformation of polymeric chain should be described by self-avoiding random walks statistics (SARW) but not Gaussian random walks statistics, assuming the phantom behaviour of polymeric chains. Nevertheless, Gaussian statistics is dominating at the analysis of thermodynamic, dynamic and kinetic stainings of the macromolecules conformation. This book will be useful for scientists who are engaged in the physical chemistry of polymers and their solutions.

The second edition of this textbook is identical with its fourth German edi tion and it thus has the same goals: precise definition of basic phenomena, a broad survey of the whole field, integrated representation of chemistry, physics, and technology, and a balanced treatment of facts and comprehen sion. The book thus intends to bridge the gap between the often oversimpli fied introductory textbooks and the highly specialized texts and monographs that cover only parts of macromolecular science. The text intends to survey the whole field of macromolecular science. Its organization results from the following considerations. The chemical structure of macromolecular compounds should be inde pendent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of polymers. Properties depend on structure. Solution properties are thus discussed in Part 11, solid state properties in Part Ill. There are other reasons for dis cussing properties before synthesis: For example, it is difficult to understand equilibrium polymerization without knowledge of solution thermodynamics, the gel effect without knowledge of the glass transition temperature, etc. Part IV treats the principles of macromolecular syntheses and reactions.

The intrinsic viscosities of a group of macromolecules (polysiloxanes) have been determined in benzene solution, and a relationship between these values and the viscosity-average weights has been established with the use of the Mark-Houwink equation.

Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

This volume commemorates the 50th anniversary of the appearance in Volume 4 in 1948 of Dr. Jeffries Wyman's famous paper in which he "laid down" the foundations of linkage thermodynamics. Experts in this area contribute articles on the state-of-the-art of this important field and on new developments of the original theory. Among the topics covered in this volume are electrostatic contributions to molecular free energies in solution; site-specific analysis of mutational effects in proteins; allosteric transitions of the acetylcholine receptor; and deciphering the molecular code of hemoglobin allostery.

Knowledge of thermodynamics is a necessary tool for describing and understanding the physical behavior of new polymers and polymer blends, for instance, compatibility of components, rheological properties, morphological features, and mechanical properties. This book summarizes in a fairly comprehensive manner the recent technical research accomplishments in the area of thermodynamics, characterizations, and applications of polymer blends. In the first chapter, an overview of thermodynamic behaviors of non-equilibrium polymers is discussed. In the consecutive chapters, different properties of polymer blends are discussed, including surface tension, transition, crystallization, morphology, and flow behaviors. Miscibility and molecular characterizations of polymer blends are also covered in this book. Applications to various systems are reviewed, and both experimental concerns and references are supplied. In this time when science has such a strong tendency for diversification, this book demonstrates the relevance of one’s own activities with neighboring branches of activities. This book is unique in that the mathematics of the physics of polymers are minimized in order not to discourage the interest of a junior or senior undergraduate or new graduate student by an unnecessarily rigorous approach. However, book aims to widen the readers’ general knowledge with a better understanding of the physics of polymers. Applications to various systems are reviewed, and both experimental concerns and references are supplied.
