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 copulverizing a halogen containing magnesium compound, e.g. MgCl 2 , with an active hydrogen containing organic compound, e.g. phenol, to produce a copulverized product. The copulverized 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 copulverized with a complex of a first titanium halide compound and an electron-donor, e.g. TiCl 4 .ethyl benzoate, to produce a solid reaction product. The solid reaction product is then reacted with a second titanium halide compound, e.g. TiCl 4 . n 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. |
