Patent number: 8044225Abstract: A zwitterionic Group VIII transition metal complex containing the simple and relatively small 3-(arylimino)-but-1-en-2-olato ligand that catalyzes the formation of polypropylene and high molecular weight polyethylene. A novel feature of this catalyst is that the active species is stabilized by a chelated olefin adduct. The present invention also provides methods of polymerizing olefin monomers using zwitterionic catalysts, particularly polypropylene and high molecular weight polyethylene.Type: GrantFiled: September 12, 2006Date of Patent: October 25, 2011Assignee: The Regents of the University of CaliforniaInventors: Guillermo C. Bazan, Yaofeng Chen
