ABSTRACT:
An improved supported chromium oxide catalyst, a process for preparing the catalyst and a process for polymerizing olefin monomers utilizing the catalyst are provided. In accordance with the preparation process, chromium oxide and a support containing one or more of silica, titania, thoria, alumina, zirconia or aluminophosphates are combined, impregnated with a metal salt and activated. The metal salt is selected from the group consisting of alkali metal salts, alkaline earth metal salts and mixtures thereof.
