摘要： An improved catalyst system is disclosed for use in the polymerization or copolymerization of olefins. The catalyst comprises a transition metal compound, an organometal compound and a composite carrier. This carrier is constituted by a SO.sub.3 treated alumina and a magnesium and/or a calcium compound. The polymerization or copolymerization of olefins such as ethylene, propylene and 1-butene is effected under conditions similar to those for reactions by means of Ziegler catalysts, but the resulting polyolefins have a wider molecular weight distribution, viz, a larger flow parameter as required for extrusion or blow molding.

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.
