A polymer consists of macromolecules which are made up of many repeated subunits. Polymer science is a multi-disciplinary science that involves characterization, designing and fabrication of various polymers. Plastics and elastomers are the primary focus of this discipline. Macromolecular chemistry, polymer physics and polymer characterization are the three primary sub-disciplines of this field. The chemical synthesis and chemical properties of polymers are studied within macromolecular chemistry. Polymer physics focuses on the engineering applications and bulk properties of polymer materials. Polymer characterization delves into the morphology and chemical structures of polymers. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of polymer science and technology. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of this field. This book includes contributions of experts and scientists which will provide innovative insights into this field.
