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.

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.

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.

"Macromolecules" provides a broad survey of the entire subject; integrated representations of chemistry, physics, and technology; precise descriptions and definitions of basic phenomena; and balanced treatments of facts and theory. The book series thus intends to bridge the gap between introductory textbooks and the highly specialized texts and monographs that cover only part of polymer science and technology. Volume I is concerned with the fundamentals of chemical structure and principles of synthesis of macromolecules: constitution, configuration, conformation, polymerization equilibria, polymerization mechanisms (ionic, coordination, free-radical, step reactions, including solid-state and biochemical polymerizations), polymer reactions, and strategies for defined polymer architectures. Volume II discusses individual polymers and their industrial syntheses, Volume III the fundamentals of physical structures and properties, and Volume IV the processing and application of polymers as plastics, fibers, elastomers, thickeners, etc. The world of macromolecules in a nutshell.

Like so many of its kind, this textbook originated from the requirements of teaching. While lecturing on macromolecular science as a required subject for chemists and materials scientists on the undergraduate, graduate, and postgraduate levels at Swiss Federal Institute of Technology at Zurich (1960-1971), I needed a one-volume textbook which treated the whole field of macromolecular science, from its chemistry and physics to its applications, in a not too elementary manner. This textbook thus intends to bridge the gap between the often oversimplified introductory books and the highly specialized texts and monographs that cover only parts of macromolecular science. This first English edition is based on the third German edition (1975), which is about 40% different from the first German edition (1971), a result of rapid progress in macromolecular science and the less rapid education of the writer. This 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 independent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of macro molecules. Properties depend on structure. Solution properties are thus discussed in Part II, solid state properties in Part III. There are other reasons for discussing properties before syntheses: For example, it is difficult to under stand equilibrium polymerization without knowledge of solution thermody of the glass temperature, etc.

Provides the tools needed to master and apply the fundamentals of polymer crystallography Using core concepts in physics, chemistry, polymer science and engineering, this book sheds new light on the complex field of polymer crystallography, enabling readers to evaluate polymer crystallization data and determine the best methods to use for their investigations. The authors set forth a variety of tested and proven methods for analyzing ordered and disordered structures in polymer crystals, including X-ray diffraction, electron diffraction, and microscopy. In addition to the basics, the book explores several advanced and emerging topics in the field such as symmetry breaking, frustration, and the principle of density-driven phase formation. Crystals and Crystallinity in Polymers introduces two new concepts in crystallinity and crystals in synthetic polymers. First, crystallinity in polymeric materials is compatible with the absence of true three-dimensional long-range order. Second, the disorder may be described as a structural feature, using the methods of X-ray scattering and electron diffraction analysis. The book begins by introducing the basic principles and methods for building structural models for the conformation of polymer crystal chains. Next, it covers: Packing of macromolecules in polymer crystals Methods for extracting structural parameters from diffraction data Defects and disorder in polymer crystals Analytical methods for diffuse scattering from disordered polymer structures Crystal habit Influence of crystal defects and structural disorder on the physical and mechanical properties of polymeric materials Crystals and Crystallinity in Polymers examines all the possible types of structural disorder generally present in polymer crystals and describes the influence of each kind of disorder on X-ray and electron diffraction patterns. Its comprehensive, expert coverage makes it possible for readers to learn and apply the fundamentals of polymer crystallography to solve a broad range of problems.

Structural Order in Polymers presents the increasing importance of the relationships between order in the chemical constitution and in the steric structure of the macromolecules and physical and chemical properties of the polymers. This book discusses the simple types of steric order found in biopolymers. Organized into three parts encompassing 16 chapters, this book begins with an overview of the structural regularity as a primary requisite for the crystallization of a polymer. This text then examines the structure of cellulose, which is the most significant structural stereoregular polymer. Other chapters consider the major concepts of the stereoregulation of propylene catalytic polymerization. This book discusses as well the factors that determine microstructure and stereospecifity in polymerization. The final chapter deals with the significant role that membranes and membrane-related processes play in solving many ecological problems. This book is a valuable resource for chemical engineers, chemists, physicists, scientists, and research workers.
