Polymers In Solution

Polymer Solutions: An Introduction to Physical Properties offers a fresh, inclusive approach to teaching the fundamentals of physical polymer science. Students, instructors, and professionals in polymer chemistry, analytical chemistry, organic chemistry, engineering, materials, and textiles will find Iwao Teraoka’s text at once accessible and highly detailed in its treatment of the properties of polymers in the solution phase. Teraoka’s purpose in writing Polymer Solutions is twofold: to familiarize the advanced undergraduate and beginning graduate student with basic concepts, theories, models, and experimental techniques for polymer solutions; and to provide a reference for researchers working in the area of polymer solutions as well as those in charge of chromatographic characterization of polymers. The author’s incorporation of recent advances in the instrumentation of size-exclusion chromatography, the method by which polymers are analyzed, renders the text particularly topical. Subjects discussed include: Real, ideal, Gaussian, semirigid, and branched polymer chains Polymer solutions and thermodynamics Static light scattering of a polymer solution Dynamic light scattering and diffusion of polymers Dynamics of dilute and semidilute polymer solutions Study questions at the end of each chapter not only provide students with the opportunity to test their understanding, but also introduce topics relevant to polymer solutions not included in the main text. With over 250 geometrical model diagrams, Polymer Solutions is a necessary reference for students and for scientists pursuing a broader understanding of polymers.

Polymers in Solution was written for scientists and engineers who have serious research interests in newer methods for characterization of polymer solutions, but who are not seasoned experts in the theoretical and experimental aspects of polymer science. In particular, it is assumed that the reader is not familiar with the development of theoretical notions in conformational statistics and the dynamics of chainlike molecules; how these two seemingly diverse theoretical topics are related; and the role played by polymer-solvent interactions. Chapter 1 thus presents background material that introduces most of the essential concepts, including some of the mathematical apparatus most commonly used in these areas of theory. This introduction is followed by five chapters that are more closely related to particular experimental techniques. These chapters introduce further theoretical notions as needed. Three of the chapters present con siderable detail on the experimental methods, while two other chapters deal more with the interpretation of experimental results in terms of current theories. Although neutron scattering has become an almost standard technique for the study of conformational properties of macromolecules in the solid state, there has been less emphasis on its application for characterization of polymer molecules in solution. Chapter 4 covers this growing area of application.

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.

This book is devoted to the static properties of flexible polymers in solution, presenting the vast theoretical and experimental progress made in recent years. Work in this area has been especially fruitful because long polymer chains show a universality in their behavior when in solution, despite the variety in their chemical composition and physical properties. The authors include the results of new experimental techniques such as photon and neutron scattering, and the use of computer simulations. This work is the result of a collaboration between a theoretician and an experimentalist, who have both worked for many years on polymer solutions.

This volume contains a series of papers originally presented at the symposium on Water Soluble Polymers: Solution Properties and Applications, sponsored by the Division of Colloids and Surface Chemistry of the American Chemical Society. The symposium took place in Las Vegas City, Nevada on 9 to 11th September, 1997 at the 214th American Chemical Society National Meeting. Recognized experts in their - spective fields were invited to speak. There was a strong attendance from academia, g- ernment, and industrial research centers. The purpose of the symposium was to present and discuss recent developments in the solution properties of water soluble polymers and their applications in aqueous systems. Water soluble polymers find applications in a number of fields of which the following may be worth mentioning: cosmetics, detergent, oral care, industrial water treatment, g- thermal, wastewater treatment, water purification and reuse, pulp and paper production, sugar refining, and many more. Moreover, water soluble polymers play vital role in the oil industry, especially in enhanced oil recovery. Water soluble polymers are also used in ag- culture and controlled release pharmaceutical applications. Therefore, a fundamental kno- edge of solution properties of these polymers is essential for most industrial scientists. An understanding of the basic phenomena involved in the application of these polymers, such as adsorption and interaction with different substrates (i. e. , tooth enamel, hair, reverse - mosis membrane, heat exchanger surfaces, etc. ) is of vital importance in developing high performance formulations for achieving optimum efficiency of the system.

This is the first self-contained book on the thermodynamics and critical phenomena of polymer solutions, ranging from the rather elementary level to the advanced and up-to-date level. The book covers the rigorous theories of phase equilibrium, computer experiments based on these theories, as well as actual experiments, molecular fractionation and application to membrane and fiber production. An extensive list of references and literature data on the thermodynamic interaction x-parameter, critical point, fractionation and polymer blends is also provided. This book should prove invaluable for courses on polymer science, thermodynamics and polymer solutions at graduate, university and polytechnic level.

Created for engineers and students working with pure polymers and polymer solutions, this handbook provides up-to-date, easy to use methods to obtain specific volumes and phase equilibrium data. A comprehensive database for the phase equilibria of a wide range of polymer-solvent systems, and PVT behavior of pure polymers are given, as are accurate predictive techniques using group contributions and readily available pure component data. Two computer programs on diskettes are included. POLYPROG implements procedures given for prediction and correlation for specific volume of pure polymer liquids and calculation of vapor-liquid equilibria (VLE) of polymer solutions. POLYDATA provides an easy method of accessing the data contained in the many databases in the book. Both disks require a computer with a math coprocessor. This handbook is a valuable resource in the design and operation of many polymer processes, such as polymerization, devolatilization, drying, extrusion, and heat exchange.
