Abstract
A process for producing an olefin polymer by polymerizing an olefin with a catalyst system comprising an organoaluminum compound and a supported catalyst component prepared by using as the carrier a solid product obtained by the reaction of an organomagnesium compound with an aluminum halide compound and/or a silicon halide compound, by heating a liquid ether complex of titanium trichloride in the presence of said carrier, and further reacting the resulting titanium trichloride-containing solid product with titanium tetrachloride. By this process, the olefin polymer having a broad molecular weight distribution suitable for flow molding or extrusion molding is produced.
