This book deals with the problems of the thermodynamics of systems containing flexible-chain polymers as the basis of polymer material science. The main thermodynamic quantities and concepts are introduced and discussed in the order of the objects getting more and more complicated: gases, magnets, low-molecular-weight substances and mixtures, and finally, polymers and polymer blends.All topics are considered in a common clue, using the principle of universality. The stability conditions for the one-phase state of multi-component systems are given. Phase separation is regarded as a result of loss in stability. The critical state of a system, with the one-phase state being close to the boundary of stability conditions breaking, is discussed in detail. The effects of both light scattering (elastic and dynamic) and diffusion, as directly depending on the thermodynamic parameters characterizing the one-phase state stability, are considered in detail. One of the versions of colloid scattering, namely, the turbidity spectrum method, is described as useful for the characterization of various heterogeneous structures and for the phase analysis of polymer systems. In the approximation of mean field theories and advanced field theory, formalisms expound the following divisions of the thermodynamics of binary and polynary systems with flexible-chain polymers: conformation of the polymer coil, composition fluctuations, elastic and dynamic light scattering, diffusion in the one-phase state (including the critical range), phase separation, polymer fractionation, the coil-globule transition, phase equilibrium and separation in the system network polymer + low-molecular-weight liquid, polymer blends and multiphase separation.

This handbook provides the only complete collection of high-pressure thermodynamic data that is essential for understanding polymer solutions. It contains data on vapor-liquid equilibria and gas solubilities, liquid-liquid equilibria, high-pressure fluid phase equilibria for polymer systems in supercritical fluids, enthalpic and volumetric data, as well as second virial coefficients all at elevated pressures. It covers all areas needed by researchers and engineers who handle polymer systems in supercritical fluids; materials science and technological applications such as computerized predictive packages; and chemical and biochemical processes, such as synthesis and characterization, fractionation, separation, purification, and finishing of polymers and related materials.

Providing the necessary basis for any developments of theoretical thermodynamic models, this book provides a complete collection of practical thermodynamic data for a variety of applications, including: basic and applied chemistry, chemical engineering, thermodynamic research, computational modeling, membrane science and technology, and environmental and green chemistry. The data -- which includes such developments as vapor-liquid and liquid-liquid equilibria, low-and high-pressure equilibrium data, enthalpic and volumetric data, and second virial coefficients -- is necessary when studying intermolecular interactions and gaining insights into the molecular nature of mixtures.

This book provides the most recent studies on interferometry and its applications in science and technology. It is an outline of theoretical and experimental aspects of interferometry and their applications. The book is divided in two sections. The first one is an overview of different interferometry techniques and their general applications, while the second section is devoted to more specific interferometry applications comprising from interferometry for magnetic fusion plasmas to interferometry in wireless networks. The book is an excellent reference of current interferometry applications in science and technology. It offers the opportunity to increase our knowledge about interferometry and encourage researchers in development of new applications.

Polymeric materials include plastics, gels, synthetic fibres, and rubbers. They are all-important both in industry and in daily life. Unlike liquid water, ice, or sugar solution, polymers are not homogeneous. They are said to consist of two or more phases, and their production and processing, as well as their properties and uses, depend on an understanding of the transitions that take place between these phases. This new textbook uses fundamental principles to classify phase separation phenomena in polymer systems, and describes simple molecular models explaining the observed behaviour.

Thermodynamic data form the basis for separation processes used in different fields of science and industry, from specialty chemicals to foods and pharmaceuticals. One obstacle to developing new production processes, products, or optimization is the lack, or inaccessibility, of experimental data related to phase equilibrium. Access More Than 1200 Data Sets, Including 810 Binary Systems, 325 Ternary Systems, and 25 Quaternary (or Higher) Systems The CRC Handbook of Liquid-Liquid Equilibrium Data of Polymer Solutions provides a thorough and up-to-date compilation of experimental liquid-liquid equilibrium (LLE) data and their original sources. Arranged in a consistent format, the handbook provides convenient access to cloud-point and coexistence data as well as upper and lower critical solution temperatures and important demixing data for each system. An Excellent Companion to the Author’s Previous Collections of Thermodynamic Data! While the author’s previous data compilations center around specific types of polymer systems, Wohlfharth’s latest work distinguishes itself by focusing instead on representing LLE data for all types of polymer systems in a single source.
