Job, R C

This patent describes a process of producing a lower [alpha]-olefin polymer. It comprises contacting under polymerization conditions one or more lower [alpha]-olefins with an olefin polymerization catalyst obtained by contacting a catalyst component obtained by contacting a magnesium dialkoxide wherein each alkoxide independently has up to 4 carbon atoms conclusive, titanium tetraalkoxide wherein each alkoxide independently has up to 4 carbon atoms inclusive, and a phenolic compound selected from phenol and activating group-substituted phenol, at elevated temperature, with a tetravalent titanium halide and an electron donor, with an organoaluminum cocatalyst and a selectively control agent.
