    Abstract: A polymerization catalyst obtained by contacting metallic magnesium with an aromatic halide, RX, under conditions effective to obtain a first reaction product and solid residual products is disclosed. The first reaction product is then separated from the solid residual products. A silane compound containing an alkoxy or aryloxy group is added to the first reaction product between −20° C. to 20° C. to obtain a precipitate which is purified to obtain a second reaction product. Subsequently, the second reaction product is contacted with a halogenized titanium compound, such as, titanium tetrachloride, to obtain a further reaction product. The polymerization catalyst is obtained by purifying the further reaction product. In the aromatic halide, R represents an aromatic group containing from 6 to 20 carbon atoms and X represents a halide. An electron dopor such as dibutyl phthalate may also be present during the titanium addition.
