In recent years, multicomponent polymers have generated much interest due to their excellent properties, unique morphology, and high-end applications. This book focuses on thermal, thermo-mechanical, and dielectric analysis of polymers and multicomponent polymeric systems such as blends, interpenetrating polymeric networks (IPNs), gels, polymer composites, and nanocomposites. Through these analyses, it provides an insight into the stability of polymer systems as a function of time, processing, and usage. Aimed at polymer chemists, physicists, and engineers, it also covers ASTM/ISO and other standards of various measurement techniques for systematic analysis in materials science.
