Chain Structure and Conformation of Macromolecules provides an introduction to the chain structures of synthetic polymers and their determination in solution and in the solid state. This book discusses the synthetic methods and polymerization mechanisms. Organized into eight chapters, this book begins with an overview of the brief history of the macromolecular concept and of stereochemical and geometrical isomerism in synthetic polymer chains. This text then introduces vibrational spectroscopy and nuclear magnetic resonance spectroscopy. Other chapters consider the geometric isomerism in diene copolymers as well as the rotational isomeric state method of calculation of polymer chain dimensions. This book discusses as well copolymerization and the measurement of copolymer structure. The final chapter deals with the NMR observation of polymers in the solid state by the method of magic angle spinning, by which both dynamic measurements and high resolution structural information are possible. This book is a valuable resource for organic chemists, chemical engineers, and research workers.

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.

Conformational Properties of Macromolecules provides information about the molecular parameters and spatial and thermodynamic properties of macromolecules and the application of theoretical conformational energy calculations. The book covers topics such as macromolecular geometry, the classification of macromolecular structure, and the generation of macromolecular conformations and configurations; conformational energies and potential functions, induced dipole and polymer-solvent interactions; and conformational transition in molecules. Also covered are topics such as absorption and optical rotation spectroscopies, epitaxial crystallization of macromolecules, and conformational fluctuation in macromolecules. The text is recommended for structural chemists, X-ray crystallographers, biophysicists, physical chemists, and macromolecular scientists who would like to know more about this particular area of knowledge.

On the day after the 1959 Cambridge Congress, during which the International Union of Pure and Applied Biophysics was founded, a biophysics section was formed within the Society of Physical Chemistry (Societe de Chimie Physique). Since then, three of the Society's annual meetings (the 11th, 17th, and 23rd) were devoted exclusively to the physico-chemical study of biological systems. The first of these was held in June 1961 at a hotel in Col de Voza, at the foot of an alpine glacier above Chamonix. The second, in May 1967, took place in the more learned setting of the venerable rooms of the National Museum of Natural History in Paris. The third - the one dealt with in the present volume - was recently held at Orleans-La Source in the newly built lecture theatres of the young University, which is near the great Institutes of the National Centre for Scientific Research (CNRS), on the Sologne plateau. These three stages are milestones of an evolution which characterises (at least schematically) the explosive evolution of biological physico-chemistry. The first colloquium, with the title 'Deoxyribonucleic Acid: Structure, Synthesis and Functions', actually marks the first contact of the physical chemist with one of the then most prestigious biological macromolecules, the structure of which had just been discovered, and in this way celebrated one of the first and most striking successes of molecular biology.

Macromolecular materials possess some remarkable features arising from the fact that their molecules are made up of more or less flexible chains which can have various conformations. The study of molecular conformations and dynamics of macromolecules is important in polymer science and technology from both basic and practical viewpoints. In practice, these studies have concentrated on dilute solutions but more recently there has been a clear trend towards studying molecular properties in condensed systems in order to understand the entire macromolecular system based on a unified concept.Based on lectures presented by an internationally recognized group of polymer scientists at a meeting held in Japan in October 1987 (plus two additional contributions), this volume summarises present knowledge of molecular conformations and dynamics of macromolecules from dilute solutions to various condensed systems. The book is not a random collection of papers of the usual conference proceedings type. Authors prepared their contributions in line with an overall plan for the work, were able to discuss the content with colleagues at the meeting, and finalised their text after the conference. It is thus a comprehensive, integrated overview of the field. Current developments in both theory and experiment are discussed in a well-balanced way. The behaviour of macromolecules at phase transition and interface is discussed in relation to their behaviour in bulk systems.The book offers a particularly up-to-date and authoritative picture of the current state of the art, and will be of interest to all research and professional workers concerned with polymer science in universities, industry, and government institutions.

The reception of the original volume by students, pedagogues, and reviewers has been most gratifying. It appears to have both satisfied a need and served a useful educational purpose. Hence, some ten years later it has been deemed advisable to bring it up to date, if only in a slightly expanded form. The purpose for writing this book and its level remain the same. Many new polymers have been synthesized in the last decade that have found meaningful and novel uses. Examples of these applications are included in this new edition. Major advances have also been made in biophysics and in molecular biology, as well as in our understanding of natural processes on a molecular level. Foremost among these has been the development of recombinant DNA technology. With it has come the potential for large scale synthesis of hormones and proteins. These new developments have also been incorporated into the present volume. It is my hope that this new edition will still have a widespread appeal to students in all of the natural sciences whatever their major interest. It should also be of use and inter est to those starting industrial or academic careers who have not had an extensive background in macromolecular science.

The determination of the three-dimensional structure of a biological molecule is the starting point in the understanding of molecular mechanisms involved in its complex biochemical reactions. The molecular architecture of multimolecular systems such as membranes and chromosomes provides the key to the fascinating field of molecular biology. Stereochemical details of biological macromolecules and their interactions with pharmacological agents form the basis for drug design. Naturally, the study of the structure and function of biological molecules has aroused tremendous interest and investigations in this area are being carried out in a large number of laboratories. The techniques used for this purpose include both experimental methods (X-ray and neutron diffraction measurements, study of NMR, ESR, vibrational and electronic spectra, ORD, CD and dipole moment measurements, biochemical modifications etc. ) and the oretical methods (quantum mechanical and classical potential energy calculations, Monte Carlo simulations and molecular graphics). F or several years now, X-ray diffraction [1] has served as our only source of infor mation on the three-dimensional arrangements of atoms in biopolymers. Fiber-diffrac tion of DNA led to the proposal of the DNA double helix. Fibers of long~hain polymers show ordering in the direction of the fibre-axis but not in the transverse plane. Accurate estimates of the dimensions of helical structures can be made using techniques on the basis of which models of biopolymers can be constructed.
