ABSTRACT:
Alpha olefins are polymerized in the presence of catalyst compositions which are the catalytic reaction products of (A) the reaction product or complex resulting from the mixing of (1) a mixture of a transition metal compound such as a tetraalkoxy titanium compound, a non-metallic oxygen-containing compound such as an alcohol and (2) a reducing alkylating agent such as a dialkyl magnesium compound and (B) a magnesium halide.
