ABSTRACT:
Improved lower .alpha.-olefin polymerization catalysts are produced from an organoaluminum cocatalyst, a selectivity control agent and a specified magnesium-containing, titanium-containing, halide-containing procatalyst. The procatalyst is produced from an electron donor, tetravalent titanium halide and a complex alkoxide compound formed from magnesium alkoxide, titanium alkoxide and a phenolic compound. The catalyst is utilized to produce poly-.alpha.-olefin in good yield, which polymer is characterized by a relatively low xylene solubles content and a relatively high bulk density.
