Abstract: Process for polymerizing an alkene-1, ethylene or mixtures thereof by employing a catalyst which comprises (1) a titanium component which is a titanium halide supported on a magnesium-dihalide or manganese-dihalide support and (2) an organoaluminum component which comprises (a) a complex of an aluminum trialkyl and an ester of a carboxylic acid and an alcohol and (b) the reaction product of a dialkyl magnesium compound and an alkyl-aluminum dihalide, which results in a polymer of high stereospecificity.

Abstract: l-Alkenes are polymerized or copolymerized using a catalyst system comprising a titanium halide, optionally complexed with a Lewis base, on an anhydrous magnesium- or manganefe-halide carrier and an organo-aluminum component consisting of a complex of an ester of a carboxylic acid and a trialkyl-aluminum, and a dialkyl-aluminum halide.
