ABSTRACT:
A catalyst useful in the polymerization of olefinic compounds and particularly 4-methyl-1-pentene is disclosed along with its method of preparation and use. The catalyst is prepared by (a) forming a first component by reacting reactants comprising a magnesium dihalide, a phenol, and alkylbenzoate, and a titanium tetrahydrocarbyloxide; (b) reacting the first component with an organoaluminum halide compound to produce a solid product; and (c) then contacting the resulting solid product with an activating liquid comprising titanium tetrachloride and trichlorosilane in a confined zone under pressure of at least 70 psi.
