    摘要: Pillared clay based 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 pillared clay 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 process produces catalyst components shaped like dipyramidal or generally "football"-shaped crystals.

    摘要: In accordance with a first embodiment of this invention, a silica xerogel is aqueously impregnated with a titanium compound which is resistant to hydrolysis. In accordance with a second embodiment of this invention, a silica hydrogel containing a titanium compound resistant to hydrolysis is dried. In this embodiment, the hydrogel preferably also contains a pore preserving agent. This invention makes possible the use of aqueous impregnation of titanium and conventional drying techniques to give a catalyst having characteristics associated with azeotrope dried silica-titanium coprecipitated catalyst. The catalysts of this invention are useful in olefin polymerization processes, particularly in the polymerization of predominantly ethylene monomer systems under slurry conditions.
