Abstract
A catalyst composition for alpha olefin polymerization is provided. The catalyst composition is prepared by a process including treating PVC containing particles with an organomagnesium compound in an inert solvent, contacting the treated PVC containing particles with a transition metal compound from the group TiCl , VCl or ZrCl , in the absence of an electron donor, and activating the product particles with a cocatalyst. An organoaluminum compound can also be mixed with the organomagnesium compound prior to treating the PVC containing particles.
