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.

High Resolution NMR of Macromolecules presents the development in the NMR study of polymers. This book discusses the exciting area of application of NMR to polymer science as the result of the more general accessibility of instruments of high magnetic field. Organized into 15 chapters, this book begins with an overview of the spectral analysis and the dependence of chemical shifts and J couplings on structure. This text then discusses the isomerism in polymer chains without special reference to NMR. Other chapters consider the interpretation of synthetic polymer spectra in terms of structure, stereochemical configuration, conformation, and chain growth mechanism. This book discusses as well the application of high resolution NMR to the study of nucleic acids, which has not been so well developed as that of polypeptides and proteins. The final chapter deals with biopolymers and their model compounds. This book is a valuable resource for chemists and research workers.

Biopolymers deals with the methods of physical characterization and the principles underlying them, with emphasis on quantitative aspects of sequence, conformation, and structure in both laboratory-synthesized and native biopolymers. The book reviews structural units of biopolymers and describes characterization of biopolymers, the available techniques, the evaluation of underlying principles, and experimental applications. Some of these methods include Raman spectroscopy, theoretical conformation analysis, electron microscopy, and morphology of laboratory-synthesized polymers. The text explains the factors controlling conformation of polypeptides, the steric maps of dipeptides, potential energy maps, and the calculation of tertiary polypeptide structure. The investigator can use X-ray diffraction to determine the structure of polymers and macromolecules, such as diffraction by a crystal, by poorly crystalline polymer systems, or by a helical chain. The book notes that materials that can be crystallized from strong solvents reveal morphology similar to that of commercial polymers, which are different from that of polypeptides or proteins in native tissue. The text explains the basis of infrared and Raman spectroscopy in probing molecular structure and conformation of biological macromolecules. The investigator can also employ nuclear magnetic resonance and dielectric relaxation for conformation in physical organic chemistry, outside of biological macromolecule applications. The book can prove helpful for researchers in ultra-trace analysis, polymer research, and analytical chemistry.

There is great commercial interest in hyperbranched polymers from manufacturers of polymer formulations, additives and coatings, polymer electronics and pharmaceuticals. However, these polymers are difficult to characterize due to their very complex, multidimensional distribution and there is a great need to understand how to control their synthesis to obtain certain material properties. Hyperbranched Polymers is the first book to examine in detail the recent advances in hyperbranched polymers. Focusing on the structural characterization of hyperbranched polymers, the book summarizes the research in the field and makes a direct correlation between the chemical structure and global molecular properties. This correlation is essential for understanding the structure–properties relation and fills the gap between the synthetic advances and physico-chemical understanding of this polymer class. Written by acknowledged experts in the field, the book will appeal to both scientists working in fundamental research, as well as industrial manufacturers of dendritic polymers.

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 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.
