ABSTRACT:
An improved olefin polymerization process employs an olefin polymerization catalyst produced from a polymerization procatalyst made from a magnesium alkoxide, a titanium tetraalkoxide, a tetravalent titanium halide, a phenolic compound and an alkanol. The procatalyst precursor is contacted with a tetravalent titanium halide and an electron donor to form the procatalyst which is subsequently converted to the olefin polymerization catalyst by contact with a cocatalyst and a selectively control agent.
