    摘要: A supported titanium catalyst component is produced by cogrinding in the presence of an ethylenically unsaturated hydrocarbon an organo aluminum catalyst component with a supported titanium (IV) halide on a magnesium halide until the intensity of the 14.8.degree. and 30.2.degree. x-ray diffraction peak of magnesium halide are reduced in intensity. The resulting supported titanium halide catalyst component, when employed with an organo aluminum catalyst component to form a catalyst system is highly useful for the stereoregular polymerization of .alpha.- olefins as well as the copolymerization of .alpha.-olefins.

    摘要: A supported titanium catalyst is produced by cogrinding, in combination, a magnesium halide, tetravalent titanium halide, organic acid ester, and a halogen compound selected from organic halogen compounds and halogen-containing compounds of Group IVa elements of the Periodic Table except carbon, and then treating the resulting titanium-containing solid with a hydrocarbon and/or a halogen compound as described above. The resulting supported titanium catalyst, when employed as a titanium component with an organo aluminum catalyst component for the catalyst system in a process for stereoregular polymerization of .alpha.-olefins results in unexpectedly high polymerization activity and high stereoregular polymer yielding ratios.

    摘要: A titanium trichloride catalytic complex is produced by reducing titanium tetrachloride with an organo-metal compound and then treating the resulting reduced solids product with a chlorinated saturated hydrocarbon having two carbon atoms in the presence of a complexing agent. The resulting titanium trichloride complex composition, when employed as a co-catalyst with an organo-metal compound for Ziegler-type catalysts in polymerization of .alpha.-olefins, results in uniform polymer grains with unexpectedly high polymerization activity and high stereoregular polymer yielding ratios.
