Abstract: An organic halide is added dropwise to magnesium metal in the absence of an ether or other complexing diluent, preferably in the absence of any extraneous diluent produce a magnesium reducing agent. The resulting magnesium reducing agent is then washed with an unreactive liquid hydrocarbon. An organoaluminum compound is mixed with the magnesium reducing agent either before or after the washing. The resulting cocatalyst produced by contacting the magnesium reducing agent with the organoaluminum compound is contacted with a titanium tetrahalide to give a catalyst. This catalyst is useful in the polymerization of 1-olefins and is of particular utility in the polymerization of ethylene at high productivity rates.

Abstract: A catalyst composition can be obtained by gently milling a milled mixture of a magnesium halide and a titanium tetrahalide with a magnesium alkoxide. The catalyst composition can be combined with a metallic hydride or, preferably, an organometallic co-catalyst, e.g., an organoaluminum compound, to form a catalyst useful for the polymerization of alpha-ole-fins.

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