摘要: A process for the production of polyolefins using an improved catalyst which exhibits enhanced activity in the polymerization or copolymerization of olefins such that the yields of the polymers or copolymers are increased with a minimum catalyst residue remaining. The catalyst is produced by reacting a magnesium dihalide anhydride with an aluminum alkoxy compound to produce a carrier on which a titanium compound and/or a vanadium compound is applied. The molar ratio of magnesium dihalide to aluminum compound ranges between 1:0.001 to 1:20, and most effectively is in the range of 1:0.05 to 1:5.
