Chromatographic Characterization of Polymers: Hyphenated and Multidimensional Techniques

H

his important new volume presents an overview of some of the significant developments in the use of hyphenated multidimensional separation methods for polymer characterization. Divided into three sections, the book covers: • general considerations • light scattering and viscometry • analysis of compositional heterogeneity and blends. Among the chromatographic separation techniques discussed are: size-exclusion chromatography, liquid chromatography, and field-flow fraction methods used in conjunction with information-rich detectors such as molecular size- or compositional-sensitive detectors and that are coupled in cross-fraction modes. Valuable reading for both academic and industrial scientists developing chromatographic methods for polymers or conducting polymer research. Theodore Provdor, The Glidden Company, Editor Howard G.
