<p>Compositions exhibiting high catalytic activity in the polymerization of alpha -olefins, particularly higher olefins, are provided by reacting a trivalent titanium halide complex such as an alcohol complex of titanium trichloride, an organomagnesium component such as a hydrocarbon soluble complex of dialkyl magnesium and an airy aluminum and halide source such as a hydrogen halide or an alkyl aluminum halide.</p> |
