ABSTRACT:
A catalyst and method in which the catalyst is used with an aluminum cocatalyst in the polymerization and copolymerization of 1-olefins and is prepared by reacting a monofunctional organic silicon compound with silica, alumina, or the like followed by reacting the product of this reaction with a Group IIA organometallic compound or complex, then reacting this product with a halide or alkoxide of a metal of Group IVB or Group VB or mixtures thereof. If desired, the halide or alkoxide may be first reacted with the silicon compound reaction product before the reacting with the organometallic compound or complex.
