Book Description
Fractionation of polymers via solubility has been a well known method in polymer characterization for a long time. The original object of analytical fractionations, the determination of the molecular weight distribution, is nowadays achieved more efficiently and conveniently by chromatographic methods. However, fractionation procedures, which were developed in great diversity, remain up~to-date and essential for obtaining preparative fractions with narrow distributions. Such fractions are wanted increasingly for the investigation of true structure-property relationships which are mostly influ~ enced by distributions of molecular weight or other parameters such as branching or chemical composition. Literature on the field of polymer fractionation is extensive and several reviews exist. However, there is a lack of systematically methodical instruc tions for carrying-out of diverse fractionation procedures. This volume repre sents an attempt to reduce this deficiency and is focussed on practical aspects of fractionation procedures. This laboratory manual is intended for polymer chemists, physicists, and technicians, for students of polymer science, and skilled laboratory assistants, all of whom are not dealing directly with fractionation but are in need of fractions to carry out further investigations.

Book Description
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.

Book Description
This collection of texts written by well-recognised specialists was constituted having in view these important directions of actual research. Sustainable economical growth requires safe resources of raw materials for the industrial production. Today's most frequently used industrial raw material, petroleum, is neither sustainable, because limited, nor environmentally friendly. While the economy of energy can be based on various alter-native raw materials, such as wind, sun, water, biomass, as well as nuclear fission and fusion, the economy of substances is fundamentally depending on biomass, in particular biomass of plants. In the last decades because of the crude oil and other natural resources crisis, a new alternative has been proposed consisting in utilisation of renewable natural resources as feedstock and fuel, among which the biomass is the most promising.

Book Description
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.

Book Description
A comprehensive, practical approach to three powerful methods of polymer analysis and characterization This book serves as a complete compendium of three important methods widely used for the characterization of synthetic and natural polymers—light scattering, size exclusion chromatography (SEC), and asymmetric flow field flow fractionation (A4F). Featuring numerous up-to-date examples of experimental results obtained by light scattering, SEC, and A4F measurements, Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation takes an all-in-one approach to deliver a complete and thorough explanation of the principles, theories, and instrumentation needed to characterize polymers from the viewpoint of their molar mass distribution, size, branching, and aggregation. This comprehensive resource: Is the only book gathering light scattering, size exclusion chromatography, and asymmetric flow field flow fractionation into a single text Systematically compares results of size exclusion chromatography with results of asymmetric flow field flow fractionation, and how these two methods complement each other Provides in-depth guidelines for reproducible and correct determination of molar mass and molecular size of polymers using SEC or A4F coupled with a multi-angle light scattering detector Offers a detailed overview of the methodology, detection, and characterization of polymer branching Light Scattering, Size Exclusion Chromatography and Asymmetric Flow Field Flow Fractionation should be of great interest to all those engaged in the polymer analysis and characterization in industrial and university research, as well as in manufacturing quality control laboratories. Both beginners and experienced can confidently rely on this volume to confirm their own understanding or to help interpret their results.
