ABSTRACT:
Catalysts, especially for olefin polymerization are prepared by coating an aluminum compound on a selected high pore volume silica gel, and calcining the support at temperatures of from about 200.degree. to 2000.degree. F. The preferred catalyst is prepared with an inorganic support material as aforesaid, thereafter depositing an organophosphoryl chromium compound thereon, and activating the thus-treated support by heating in a non-reducing, preferably oxygen-containing, atmosphere at temperatures of from about 800.degree. to 2000.degree. F. The activated, supported catalyst composition may, but need not necessarily, be combined with a metallic and/or non-metallic reducing agent, to provide a catalyst system useful in the polymerization of 1-olefins.
