Presents an overview of the recent developments in the use of hyphenated multidimensional separation and detection techniques for the characterization of polymeric materials. Reports on successful multidimensional chromatographic methods and multiple detector systems. Includes an analysis of compositional heterogeneity in copolymers and blends.

Presents the methods used for characterization of polymers. In addition to theory and basic principles, the instrumentation and apparatus necessary for methods used to study the kinetic and thermodynamic interactions of a polymer with its environment are covered in detail. Some of the methods examined include polymer separations and characterization by size exclusion and high performance chromatography, inverse gas chromatography, osmometry, viscometry, ultracentrifugation, light scattering and spectroscopy.

Discerning the properties of polymers and polymer-based materials requires a good understanding of characterization. This revised and updated text provides a comprehensive survey of characterization methods within its simple, concise chapters. Polymer Characterization: Physical Techniques, provides an overview of a wide variety of characterization methods, which makes it an excellent textbook and reference. It starts with a description of basic polymer science, providing a solid foundation from which to understand the key physical characterization techniques. The authors explain physical principles without heavy theory and give special emphasis to the application of the techniques to polymers, with plenty of illustrations. Topics covered include molecular weight determination, molecular and structural characterization by spectroscopic techniques, morphology and structural characterization by microscopy and diffraction, and thermal analysis. This edition contains a new chapter on surface analysis as well as some revised problems and solutions. The concise treatment of each topic offers even those with little prior knowledge of the subject an accessible source to relevant, simple descriptions in a well-organized format.

In the last decade, the use of interaction chromatography and hyphenated techniques has become increasingly important for the characterization of polymeric materials. Interaction chromatography allows separation by other structural features than molar mass, while hyphenation with mass spectroscopy or spectroscopic techniques provides detailed characterization of the separated chromatographic fractions. This chapter gives an overview of the principles and applications of interaction chromatography and the information that can be determined by hyphenation of polymer chromatography with mass spectrometry and spectroscopic techniques.

Analytical Methods for Polymer Characterization presents a collection of methods for polymer analysis. Topics include chromatographic methods (gas chromatography, inverse gas chromatography, and pyrolysis gas chromatography), mass spectrometry, spectroscopic methods (ultraviolet-visible spectroscopy, infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance), thermal analysis (differential scanning calorimetry and thermogravimetry), microscopy methods (scanning electron microscopy, transmission electron microscopy, and atomic force microscopy), and x-ray diffraction. The author also discusses mechanical and dynamic mechanical properties.
