    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 aliphatic hydrocarbon having three to eight 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.
