Terry J Burkhardt, William B Brandley: Method for preparing metallocene catalyst systems. Exxon Chemicals Patents, Hoechst Aktiengesellschaft, C Paige Schmidt, June 3, 1997: US05635437 (10 worldwide citation)

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 resultin ...
