ABSTRACT:
Polymerization of olefins in the presence of a catalyst system comprising titanium-coating component (A) associated with a milled blend of at least two different silica-containing components having different MI (polymer melt index) potentials and a dihydrocarbylmagnesium compound, and a cocatalyst component (B) comprising an organoaluminum compound. Ethylene polymers having broad molecular weight distribution are obtained using the catalyst defined herein.
