摘要： A titanium trichloride catalytic complex is produced by reducing titanium tetrachloride with an alkylaluminum halide composition at low temperature and then treating the resulting reduced solids product by contacting it at elevated temperature with a dialkyl ether having alkyl groups of 4 to 5 carbon atoms and with hexachloroethane, the proportion of dialkyl ether being at least 1 mol per 1 mol of hexachloroethane and the proportion of hexachloroethane being at least greater than about 0.5 mol per 1 gram atom of titanium in the reduced solids product. The resulting titanium trichloride complex composition, when employed as 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.

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.
