ABSTRACT:
A titanium-containing olefin polymerization catalyst component comprises a titanium-containing component formed by reducing titanium tetrachloride with an organoaluminum compound, optionally contacting the resulting reduced solid with a pretreatment amount of alpha-olefin monomer under polymerization conditions, and reacting the resulting product with a Lewis base complexing agent and a haloalkylchlorosilane.
