Patent number: 5091490Abstract: Silica supported high activity olefin polymerization catalysts, methods of producing the catalysts and methods of using the catalysts in the polymerization of olefins are provided. The methods of producing the catalysts each basically comprise contacting a particulate silica support impregnated with tungsten oxide with the soluble complex produced by heating a mixture of a metal dihalide with a transition metal compound to produce a solid, and then reacting the solid with an organoaluminum halide. The catalysts produced have improved productivities and are less soluble in polymerization media.Type: GrantFiled: June 19, 1991Date of Patent: February 25, 1992Assignee: Phillips Petroleum CompanyInventors: Gil R. Hawley, Simon G. Kukes, Robert L. Banks, deceased
