Abstract: A magnesium reducing agent is prepared by dropwise addition of an organic halide onto magnesium metal in the absence of an ether or other complexing diluent, preferably in the absence of any e?raneous diluent, to form a magnesium reducing agent which is thereafter mixed with an organoaluminum halide to form a cocatalyst. The resulting cocatalyst is contacted with a titanium tetrahalide to give a catalyst. This catalyst is suitable for olefin polymerization and particularly suitable for the polymerization of ethylene.
