ABSTRACT:
Compositions consisting of the reaction product or complex resulting from the mixing of (1) a mixture of a transition metal compound such as a tetraalkoxy titanium compound with a non-metallic oxygen-containing compound such as an alcohol and (2) a strongly reducing alkylating agent such as a dialkyl magnesium compound are useful in the preparation of catalysts for polymerizing .alpha.-olefins at ultra-high efficiencies at high polymerization temperatures.
