This two-volume set 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 the development of advanced technologies. They have been discussed at a number of symposia on mechanochemistry and mechanical alloying in various countries.
This book will be of great interest to all experts in the area of Macromolecular Mechanochemistry.
