    • 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.
    • 通过在低温下用烷基卤化铝组合物还原四氯化钛,然后在升高的温度下将其与具有4至5个碳原子的烷基的二烷基醚和六氯乙烷接触来处理所得的还原固体产物,从而生产三氯化钛催化络合物, 每1摩尔六氯乙烷中二烷基醚的比例至少为1摩尔,并且六氯乙烷的比例在还原固体产物中至少大于约0.5摩尔/克原子钛。 所得到的三氯化钛复合物组合物当用作α-烯烃聚合中的齐格勒型催化剂的有机金属化合物作为助催化剂时,导致均匀的聚合物颗粒具有出乎预料的高聚合活性和高立体规则聚合物产率。
