Abstract

A solution process for the polymerization or copolymerization of at least one alpha olefin can include adding a Lewis acid to an alkyl aluminum in a hexane or heptane to form a coordination complex, stirring the coordination complex continuously forming a near homogeneous solution in an inert anhydrous environment, adding at least one dry metallocene to the near homogenous solution forming a soluble polymerization initiator, then stirring to form a near homogenous metallocene enriched polymerization initiator, and polymerizing an alpha olefin with the metallocene enriched polymerization initiator and optionally adding additional alkyl aluminum as a moisture scavenger or an impurities scavenger to yield a poly alpha olefin. The at least one dry metallocene can have a transition metal compound. The Lewis acid is capable of forming an ion pair with the at least one dry metallocene.
