Abstract

Method for the polymerization of alpha-olefins, e.g., ethylene and its higher homologs, to produce high molecular weight polymers by contacting the alpha-olefin or an alpha-olefin mixture to be polymerized with a catalyst formed from a mixture of a first and second component, the first component essentially consisting of a dialkyl, diaryl organoaluminum compound, or aluminum hydride, and preferably a dialkyl aluminum halide, e.g., diethyl aluminum chloride, and the second component essentially consisting of a salt, freshly precipitated oxide or hydroxide of a Group IVB, VB, VIB or VIII of the Periodic System, and most preferably a salt, such as titanium chloride.
