Radiation processing of polymer materials and itsindustrial applications

This text examines the effect of radiation on polymers and the versatility ofits industrial applications. By helping readers understand and solve problemsassociated with radiation processing of polymers, it serves as an important reference and fills a gap in the literature. Radiation processing can significantly improve important properties of polymers, however, there are still misconceptions about processing polymers by using ionizing radiation. This book explains the radiation processing of polymeric materials used in many industrial products including cars, airplanes, computers, and TVs. It even addresses emerging 'green' issues like biomaterials and hydrogels. INDICE: PREFACE. CHAPTER 1. BASIC CONCEPTS OF RADIATION PROCESSING. 1.
