This book is an extremely detailed account of all aspects of macromolecular mechanochemistry and will be of great interest to all experts in this area of rapidly advancing mechanochemistry. Mechanochemical transformations are the subject of increasing attention in solid state chemistry, physics and materials science as well as in development of advanced technologies. They have been discussed at a number of symposia on mechanochemistry and mechanical alloying in various countries. The book is divided into the following sections:Polystage feature of mechanochemical process Polymer mechanochemistry deformation Mechanodegradation Influence of some factors on mechanochemical degradation Effect of mechanodegradation on the structure and properties of polymers Polymer fracture Fracture of composite materials
