Polyamic Acids and Polyimides surveys significant developments in basic research in the chemistry and physics of polyamic acids and polyimides over the last several years. Traditional and new topics are discussed, including catalytical imidization, chemical reactions at thermal treatment, quantum-chemical study of synthesis and structure, properties of isolated molecules, and supermolecular and crystalline structures. The book will be an excellent reference for researchers, practitioners, and graduate students working with polyimides and related heat-resistant polymers and materials.
