Abstract: A titanium halide containing component suitable for use in a catalyst system comprising said component and an aluminum containing component is obtained by co-pulverizing a halogen containing magnesium compound, e.g. MgCl2, with an electron-donor compound, e.g. ethyl benzoate, to produce a co-pulverized product. The co-pulverized product is then reacted with an organic phosphite, e.g. triphenyl phosphite, to produce a reaction product. The reaction product is then reacted with a titanium halide compound, e.g. TiCl4. A catalyst system for the polymerization of alpha-olefins includes such titanium halide containing component and an organoaluminum component.

Abstract: Catalyst system for the polymerization of alphaolefins. 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 co-pulverizing a halogen containing magnesium compound, e.g. MgCl2, with an active hydrogen containing organic compound, e.g. phenol, to produce a co-pulverized product. The co-pulverized product is then reacted with an organometallic compound of a metal of Groups I to III of the Periodic Table, e.g. triethyl aluminum, to produce a reaction product. The reaction product is then co-pulverized with a complex of a first titanium halide compound and an electron-donor, e.g. TiCl4.ethyl benzoate, to produce a solid reaction product. The solid reaction product is then reacted with a second titanium halide compound, e.g. TiCl4.
