About This Book
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 polymersâlight 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.

Information
- Molar mass.
- Chemical composition: A random copolymer contains a random arrangement of the monomers and can be denoted schematically as -A-B-A-B-A-A-B-B-B-B-A-B-B-A-B-. The particular macromolecules can differ in their overall chemical composition as well as in the sequential arrangement of monomers in the polymer chain. A block copolymer contains linear blocks of monomers of the same type -A-A-A-A-A-A-A-A-A-B-B-B-B-B-B- and the possible heterogeneity includes various block length or existence of homopolymer fractions. A graft copolymer contains a linear main chain consisting of one type of monomer with branches made up of other monomers, when the molecules may differ in the number, position, and length of the branches. An alternating copolymer consists of regularly alternating units -A-B-A-B-A-B-A-B-A-B- such as, for example, in the well-known Nylon 66 (â COâ (CH2)4â COâ NHâ (CH2)6â NHâ )n and the heterogeneity is limited to the molar mass and end groups.
