ABSTRACT:
An olefin polymerization catalyst component produced by impregnating polyethylene with a pulverized solid olefin polymerization catalyst containing a Group 4b or 5b transition metal, for example a pulverized magnesium chloride containing titanium is impregnated in low molecular weight polyethylene by copulvering, then subjecting the impregnated polymer particles to shear in an inert medium at about the softening point of the polyethylene, which when used as a cocatalyst with an organoaluminum compound produces polymers of improved morphology having a more regular shape and higher bulk density than pulverized catalyst alone.
