    摘要: A catalyst system is provided comprising a titanium catalyst component produced by contacting a benzenediazonium tetrafluoroborate with a titanium tetrahalide such as titanium tetrachloride and a cocatalyst. Preferred cocatalysts are organoaluminum compounds. The catalyst system of this invention is broadly suitable for this polymerization of 1-olefins and is particularly suited for the production of high molecular weight ethylene polymers.

    摘要: Magnesium metal is contacted with an organic halide in the absence of an ether or other complexing diluent to produce a magnesium reducing agent for converting titanium tetrahalide to titanium trihalide. In a first embodiment, the magnesium metal, organic halide, and titanium tetrahalide are introduced into a mill and milled. In a second embodiment, the organic halide is metered dropwise onto the magnesium metal in the absence of any extraneous diluent, and the resulting magnesium reducing agent is thereafter added to a titanium tetrahalide and milled. In a third embodiment, an organic halide containing the titanium tetrahalide is metered dropwise onto magnesium metal in the absence of any extraneous diluent. In each instance the resulting titanium trihalide catalyst component is contacted with an organoaluminum compound activator and used for the polymerization of olefins, preferably the polymerization of propylene.

    摘要: 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.
