This book is written for undergraduate and graduate students in chemical engineering and chemistry. Designed to cover all main aspects of the field, it is written with a progressive logic, defining terms and concepts as they are introduced. The book describes and classifies polymers and copolymers, including detailed coverage of their properties. It also examines the types of chain growth and step growth polymerization and copolymerization reactions. Other main topics include polymer characterization techniques, practical experimental practices, industrial processing techniques, and commercially important polymers such as biopolymers, thermoplastics, and conducting polymers.
