Polymers occupy the pivotal position in the materials world today. Their specific properties and diversified applications are unmatched by other materials available nowadays. Their properties can be tailored made by modifying the structure, incorporation of additives, modifying the processing conditions, or by making alloys/ blends. Rapidity all round development in this area has necessitated the organization of thoughts and concepts and updating them to the current needs. This book deals essentially with various aspects of polymer science and engineering which is one of the most challenging area. Knowledge of proper raw material may be important to the persons related with material science and engineering. Proper quality control is required to meet the various governments standards for the benefits of consumers. Diversified applications of polymer are discussed in details to enhance the usage of plastic materials. Various engineering aspects and processing techniques are discussed to help the entrepreneurs. This book will be useful to the degree and post graduates students for academic interest. Technocrats working in this area can understand the various processing techniques in a simplified manner.
