Commercial Perspective on New Developments in catalysis for Olefin PolymerizationWilliam A. FraserExecutive Vice President, R&D and EngineeringUNIVATION TECHNOLOGIESP resented atSPE ANTECMay 19991 Commercial Perspective ON NEW Developments IN catalysis FOR OLEFIN POLYMERIZATIONABSTRACTO lefin polymerization catalysis is a domain of major research activity. For the last decade,much of this research has been focused in the area of metallocene catalysis , which has been atthe front line in driving important technologyrenewal in the polyolefins industry. Developmentsin metallocene catalysis have instigated muchtrade press discussion, and now emerging non-metallocene catalyst systems are adding newscope to the industry dialog. Announcements continue to flow in the trade press about theindustry s latest new catalyst discoveries. Hetero-substituted cyclopentadiene ligands coordinated with conventional Group IV metals;sterically-hindered, nitrogen-containing ligandscoordinated with a variety of transition metal centers, including late transition metals such asFe, Co, Ni, and Pd; and other heteroatom-basedtransition metal complexes have been shown to be activated with alumoxanes to form catalyticspecies that polymerize olefins to various types
