Abstract

This invention is generally directed toward a method for producing metallocene catalyst systems. Specifically, the method involves removing solid impurities from a solution of activated metallocene wherein activation has the effect of solubilizing the metallocene but not the impurities. The resulting catalyst system is higher in activity and produces polymer having excellent particle morphology with little or no reactor fouling.
