Book Description
Light scattering is a very powerful method for characterizing the structure of polymers and nanoparticles in solution. As part of the Springer Laboratory series, this book provides a simple-to-read and illustrative textbook probing the seemingly very complicated topic of light scattering from polymers and nanoparticles in dilute solution, and goes further to cover some of the latest technical developments in experimental light scattering.

Book Description
This 2-volume set includes extensive discussions of scattering techniques (light, neutron and X-ray) and related fluctuation and grating techniques that are at the forefront of this field. Most of the scattering techniques are Fourier space techniques. Recent advances have seen the development of powerful direct imaging methods such as atomic force microscopy and scanning probe microscopy. In addition, techniques that can be used to manipulate soft matter on the nanometer scale are also in rapid development. These include the scanning probe microscopy technique mentioned above as well as optical and magnetic tweezers.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
This first book to cover the interaction of polymers with radiation from the entire electromagnetic spectrum adopts a multidisciplinary approach to bridge polymer chemistry and physics, photochemistry, photophysics and materials science. The text is equally unique in its scope, devoting equal amounts of attention to the three aspects of synthesis, characterization, and applications. The first part deals with the interaction of polymers with non-ionizing radiation in the frequency-range from sub-terahertz via infrared radiation to visible and ultraviolet light, while the second covers interaction with ionizing radiation from the extreme ultraviolet to ?-ray photons. The result is a systematic overview of how both types of radiation can be used for different polymerization approaches, spectroscopy methods and lithography techniques. Authored by a world-renowned researcher and teacher with over 40 years of experience in the field, this is a highly practical and authoritative guide.
