Including recent advances and historically important catalysts, this book overviews methods for developing and applying polymerization catalysts dealing with polymerization catalysts that afford commercially acceptable high yields of polymer with respect to catalyst mass or productivity. Contains the valuable data needed to reproduce syntheses or use the catalyst for new applications Offers a guide to the design and synthesis of catalysts, and their applications in synthesis of polymers Includes the information essential for choosing the appropriate reactions to maximize yield of polymer synthesized Presents new chapters on vanadium catalysts, Ziegler catalysts, laboratory homopolymerization, and copolymerization INDICE: Notes on Contributors xvii .Preface xxix .Acknowledgments xxxiii .1 Industrial Metal Alkyls and Their Use in Polyolefin Catalysts 1Dennis B.
