摘要： A catalyst component for polymerization of olefins which is prepared by bringing a magnesium alkoxide, a halogenated hydrocarbon, and a titanium compound into contact with one another. The catalyst component together with a organoaluminum cocatalyst is used for the polymerization of olefins and especially for the homopolymerization of ethylene and copolymerization of ethylene with an .alpha.-olefin having from 3 to 10 carbon atoms.

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.
