The patent describes a process for the polymerization of an alpha olefin. It comprises contacting the alpha olefin under polymerization conditions with a catalyst prepared by reacting a hydrous magnesium dihalide composition with reactants comprising a benzoic acid ester and an alkoxytitanium compound to form a first catalyst component, then reacting the first catalyst component with an organoaluminum halide to form a solid product, then reacting the sold product with a halogenating agent comprising a titanium halide, wherein the molar ratio of water to magnesium dihalide in the hydrous magnesium dihalide composition is in the range of about 0.5/1 to 2/1 and the hydrous magnesium dihalide composition is prepared by comminuting a mixture of an anhydrous magnesium dihalide and a hydrous magnesium dihalide at least until the amount of the most highly hydrated magnesium dihalide species in the comminuted product has become substantially stabilized.
