Enhanced Acid-Carrier Activators and Catalysts for Olefin Polymerization This invention relates to the field of olefin polymerization catalyst compositions, and methods for polymerization and copolymerization of olefins, typically with the use of a sustained catalyst composition. In one aspect, this invention encompasses the pre-contact of a metallocene with an olefin or alkyne monomer and an organoaluminum compound prior to contacting such a mixture with the acid-support activator. |
