    • A process for the preparation of the former catalyst component of a catalyst for the polymerization of olefins composed of a titanium-based catalyst component and an organo aluminium compound is disclosed, which process comprises suspending (a) a fatty acid salt of magnesium and (b) dialkoxymagnesium into (c) a liquid halogenated hydrocarbon to form a first suspension, and adding said first suspension to (d) a titanium halide of the general formula: TiX.sub.4, wherein X represents a halogen atom, to be contacted for reaction to form a first reaction mixture, (e) an electron donor compound being present in at least one of the first suspension, the titanium halide and the first reaction mixture; or suspending the dialkoxymagnesium into the liquid halogenated hydrocarbon to form a second suspension, and adding said second suspension to a mixture of the titanium halide and the fatty acid salt of magnesium to be contacted for reaction to form a second reaction mixture, the electron donor compound being present in at least one of the second suspension, the mixture of the titanium halide and the fatty acid salt of magnesium, and the second reaction mixture.In the polymerization of olefins by use of the former catalyst component, both the amount of catalyst residues in the produced polymer and halogen content therein are greatly reduced with high polymerization activity per unit weight of the former catalyst component and with high yield of stereoregular polymer.
    • 公开了制备由钛基催化剂组分和有机铝化合物组成的烯烃聚合催化剂的前催化剂组分的方法,该方法包括将(a)镁的脂肪酸盐和(b )二烷氧基镁转化为(c)液体卤代烃以形成第一悬浮液,并将所述第一悬浮液加入到(d)通式TiX 4的卤化钛,其中X表示卤素原子,以进行反应以形成 第一反应混合物,(e)电子给体化合物存在于第一悬浮液,卤化钛和第一反应混合物中的至少一种中; 或将二烷氧基镁悬浮到液体卤代烃中以形成第二悬浮液,并将所述第二悬浮液加入到待接触的卤化钛和镁的脂肪酸盐的混合物中以形成第二反应混合物,电子给体化合物 存在于第二悬浮液,卤化钛和镁的脂肪酸盐的混合物中的至少一种和第二反应混合物中。 在通过使用前述催化剂组分的烯烃聚合中,所制备的聚合物中的催化剂残余物的量和其中的卤素含量都大大降低,而单一重量的前一种催化剂组分具有高的聚合活性,并且立体有规聚合物的产率高。
