Abstract

This invention is generally directed toward a catalyst system useful for polymerizing olefins. The method for preparing the catalyst of the invention provides for combining a bulky ligand transition metal catalyst with an activator that has been aged, optionally with a support. The catalyst system is useful in any polymerization process.
