ABSTRACT:
A catalyst composition for producing linear low density polyethylene with relatively narrower molecular weight distributions is described. The catalyst is formed by treating silica having reactive OH groups with a dialkylmagnesium in a solvent for said dialkylmagnesium; then adding to said magnesium-containing support a mixture of ROH and SiCl.sub.4 to form an intermediate which is subsequently treated with a transition metal to form a transition metal-containing intermediate, the catalyst precursor. The catalyst precursor is activated with a trialkylaluminum compound.
