Titanium-magnesium/manganese-aluminum catalyst and process for olefin polymerization.

摘要

Polymerization of alpha monoolefins employing a catalyst comprising (A) a component formed by intensive mixing (milling) of titanium halide, a Lewis base, anhydrous magnesium or manganese chloride, and an unsaturated additive, (B) trihydrocarbylaluminum and, optionally, a Lewis base, and optionally (C) a dihydrocarbyl aluminum halide.
