ABSTRACT:
A lower α-alkene polymerization heterogeneous solid catalyst which comprises a hydrated magnesium chloride derived procatalyst, a cocatalyst comprising an organoaluminium compound and a selectivity control agent comprising an ester or ether. The procatalyst comprises a titanium tetrahalide supported on a magnesium chloride ester complex precursor. Magnesium chloride alcoholate is reacted with an activated carbonyl compound in the presence of a hydrocarbon and/or halohydrocarbon solvent to generate insitu an internal electron donor ester component of the precursor. The precursor is reacted with a titanium tetrahalide optionally in the presence of a hydrocarbon and/or halohydrocarbon solvent.
