The study of polymers is known as polymer science. It comprises polymer physics, polymer chemistry, biophysics, and materials science and engineering. Polymer science and engineering is concerned with polymerization chemistry, polymerization catalysis, materials characterization, structure-property relationships, etc. It also deals with biomass, biorenewables, conducting polymers, biomimetic polymers, degradability and life cycle analysis, and controlled release formulations. Polymer science and engineering plays an important role in energy security, access to clean water, protection of the environment, and affordable healthcare. It focuses on every single process in the life cycle of a polymer ranging from monomer synthesis to product development. This book elucidates the concepts and innovative models around prospective developments with respect to polymer science and engineering. It unravels the recent studies in this field. This book will provide comprehensive knowledge to the readers.
