Abstract
Abstract A novel catalyst system for the polymerization of alpha-olefins is provided. The catalyst system comprises: (a) an organoaluminum containing component, e.g. triethyl aluminum, and (b) a titanium halide containing component. The titanium halide containing component is obtained by reacting a halogen containing magnesium compound, e.g. MgCl 2 , with an organic phosphite, e.g. triphenyl phosphite, to produce a reaction product. The reaction product is then co-pulverized with a complex of a titanium halide compound and an electron donor compound, e.g. TiCl 4 .ethyl benzoate, to produce a co-pulverized product. The co-pulverized product is then reacted with a titanium halide compound, e.g. TiCl 4 . A novel titanium halide containing component is provided as well as a process for producing said component. A process for the polymerization of alpha-olefins is also provided.
