ABSTRACT:
A catalyst and method in which the catalyst is used in association with an aluminum cocatalyst in the polymerization and copolymerization of 1-olefins. The catalyst is prepared by reacting certain organic silicon compounds with silica, alumina or the like having surface hydroxyl groups, or a mixture thereof, in which the silicon compound reacts with these surface hydroxyl groups, followed by reacting the product of this with an organomagnesium compound and further reacting this product with an alcohol or reacting the product with an alcohol and then with an organomagnesium compound and then with a halide or alkoxide of titanium, vanadium, zirconium or mixtures of these.
