ABSTRACT:
This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, typically using a supported catalyst composition. In one aspect, this invention encompasses precontacting a metallocene with a borinic acid or boronic acid prior to contacting this mixture with the acidic activator-support and an organoaluminum compound.
