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 multifunctional organic silicon compounds (silanes) 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 a halide or alkoxide of a Group IVB or VB transition metal such as titanium, vanadium, zirconium or mixtures of these and finally reacting this product with a Group IIA organometallic compound or compounds such as magnesium and calcium. The Group IIA organometallic compound can also be added before these transition metal compounds.
