Abstract
A magnesium reducing agent is prepared by reacting an organic halide with magnesium metal in the absence of an ether or other complexing diluent, preferably in the absence of any extraneous 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. In one embodiment, the organic halide is added dropwise to the magnesium metal.
