Polymer Fractionation focuses on the processes, reactions, and transformations involved in polymer fractionation, including chromatography, titration, and sedimentation. The selection first offers information on theoretical considerations and fractional precipitation. Topics include polydispersity of high polymers, phase relations for polydisperse systems, fractionation theory and efficiency, and fractionation by solvent evaporation. The manuscript then takes a look at fractional solution, chromatographic fractionation, and gel permeation chromatography. The book elaborates on thermal diffusion and turbidimetric titration, as well as methods of fractionation, studies of the variables, outline of the method and range of application, and elaboration of the method. The text then ponders on sedimentation, isothermal diffusion, and summative fractionation. Discussions focus on mathematical interpretation of summative data, experimental methods for the determination of diffusion constants, and methods for the determination of the diffusion coefficient distribution. The selection is a valuable source of information for readers interested in polymer fractionation.

Thermodiffusion in Multicomponent Mixtures presents the computational approaches that are employed in the study of thermodiffusion in various types of mixtures, namely, hydrocarbons, polymers, water-alcohol, molten metals, and so forth. We present a detailed formalism of these methods that are based on non-equilibrium thermodynamics or algebraic correlations or principles of the artificial neural network. The book will serve as single complete reference to understand the theoretical derivations of thermodiffusion models and its application to different types of multi-component mixtures. An exhaustive discussion of these is used to give a complete perspective of the principles and the key factors that govern the thermodiffusion process.

This interdisciplinary approach combines the chemistry and engineering involved to describe the conception and improvement of chromatographic processes. The book covers recent developments in preparative chromatographic processes for the separation of "smaller" molecules using standard laboratory equipment as well as the detailed conception of industrial chemical plants. Following an introductory section on the history of chromatography, the current state of research and the design of chromatographic processes, the book goes on to define the general terminology. There then follow sections on solid materials and packed columns process concepts. Final chapters on modeling and determination of model parameters, the design and optimization of preparative chromatographic processes and chromatographic reactors allow for the optimum selection of chromatographic systems. Essential for chemists and engineers working in the chemicals and pharmaceutical industries as well as for food technologies, due to the interdisciplinary nature of these processes.
