    摘要: 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.

    摘要: Disclosed is a process for the preparation of the former catalyst component of a catalyst for the polymerization of .alpha.-olefins composed of a titanium-based catalyst component and an organo aluminium compound. According to the above process, a magnesium halide is copulverized with aluminium isopropoxide to form a first copulverization product, to which an electron donor compound is added for copulverization to form a second copulverization product, and the second copulverization product is brought into contact with a titanium halide followed by washing with an inert organic solvent.In the polymerization of .alpha.-olefins by use of the former catalyst component as above, both polymerization activity per unit weight of the catalyst component and yield of stereoregular polymers are remarkably increased.
