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.

Among the materials found in Nature’s many diverse living organisms or produced by human industry, those made from polymers are dominant. In Nature, they are not only dominant, but they are, as well, uniquely necessary to life. Conformations: Connecting the Chemical Structures and Material Behaviors of Polymers explores how the detailed chemical structures of polymers can be characterized, how their microstructural-dependent conformational preferences can be evaluated, and how these conformational preferences can be connected to the behaviors and properties of their materials. The authors examine the connections between the microstructures of polymers and the rich variety of physical properties they evidence. Detailed polymer architectures, including the molecular bonding and geometries of backbone and side-chain groups, monomer stereo- and regiosequences, comonomer sequences, and branching, are explicitly considered in the analysis of the conformational characteristics of polymers. This valuable reference provides practicing materials engineers as well as polymer and materials science students a means of understanding the differences in behaviors and properties of materials made from chemically distinct polymers. This knowledge can assist the reader design polymers with chemical structures that lead to their desired material behaviors and properties.

Explains and analyzes polymer physical chemistry research methods and experimental data Taking a fresh approach to polymer physical chemistry, Physical Properties of Macromolecules integrates the two foundations of physical polymer science, theory and practice. It provides the tools to understand polymer science concepts and research methods, while also instructing how to analyze experimental data. Drawing on the author's own extensive research in physical properties of polymers as well as more traditional topics, this text offers detailed analysis of numerous problems in polymer science, including laboratory data and research results. Topics include: Solid-state dynamics of polymeric materials Glass transitions in amorphous polymers Semicrystalline polymers and melting transitions Viscoelastic behavior Relaxation processes Macromolecule-metal complexes Mechanical properties of linear and crosslinked polymers Filled with detailed graphs to help explain important quantitative trends, Physical Properties of Macromolecules teaches by example, ensuring comprehension of the subject as well as the methodology to implement theory, problem-solving techniques, and research results in practical situations. This resource serves as the ideal companion for government laboratories, industrial research scientists, engineers, and professionals in polymer science fields who are interested in fully grasping all aspects of physical polymer science.

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.

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.

Conformational Analysis of Polymers Comprehensive resource focusing on theoretical methods and experimental techniques to analyze physical polymer chemistry Connecting varied issues to demonstrate the impact on areas like biodegradability, environmental friendliness, structure-property relationship, and molecular design, Conformational Analysis of Polymers introduces theoretical methods and experimental techniques to analyze physical polymer chemistry. Opening with a description of fundamental concepts and then describing the conformational characteristics of various polymers, including different heteroatoms and chemical species, the text continues onto the applications of density functional theory (DFT) to polymer crystals and structure-property relationships. The book concludes by bringing these issues together to demonstrate their practical impact on different areas of the field. Various methods and techniques, including DFT, statistical mechanics, NMR, spectroscopy, and molecular orbital theory, are also covered. Written by a highly qualified author, Conformational Analysis of Polymers explores sample topics such as: Fundamentals of polymer physical chemistry: stereochemistry of polymers, models for polymeric chains, Flory-Huggins theory, and rubber elasticity Quantum chemistry for polymers: ab initio molecular orbital theory, DFT, NMR parameters, and periodic DFT of polymer crystals Statistical mechanics of polymeric chains: basic rotational isomeric state (RIS) scheme, refined RIS method, inversional-rotational isomeric state method, and probability theory for RIS scheme Experimental techniques: NMR and scattering methods Providing a timely update to the field of chain conformations of synthetic polymers and connecting fundamental theoretical approaches, experimental techniques, and case study applications; Conformational Analysis of Polymers is an essential resource for polymer chemists, physicists, and material scientists, industrial engineers who synthesize and process polymers, and academic researchers.
