  What is disclosed is a method for preparing a catalyst system and a catalyst system for polymerizing or copolymerizing an α-olefin. Catalyst component (A) is obtained by a process of reacting a magnesium complex (A-1) containing acid salts of group IB-VIIIB elements formed by contacting a magnesium halide with an acid salt solution of group IB-VIIIB metals or spherical particles adducts, an internal electron donor (A-2) of diester or diether or composite compounds, and a titanium compound (A-3). The catalyst compound (A) is contacted with a silicon compound (B) and an organoaluminium compound (C) to complete the catalyst system providing a good balance of catalyst performance in terms of activity and stereo-specificity.

  本发明公开了一种用于聚合或共聚α-烯烃的催化剂体系和催化剂系统的制备方法。催化剂组分（A）是通过以下工艺获得的：将含有 IB-VIIIB 族元素酸盐的镁复合物（A-1）与 IB-VIIIB 族金属或球形颗粒加合物的酸性盐溶液、二酯或二醚或复合化合物的内部电子供体（A-2）以及钛化合物（A-3）接触反应。催化剂化合物（A）与硅化合物（B）和有机铝化合物（C）接触，以完成催化剂体系，从而在活性和立体特异性方面实现催化剂性能的良好平衡。

  The present invention relates to catalyst components for the polymerization of olefins, and to the catalyst obtained therefrom, particularly suitable for the stereospecific polymerization of olefins, comprising Ti, Mg, halogen and an electron donor compound selected from heteroatom containing esters of malonic acids (hereroatom containing malonates). Said catalyst components when used in the polymerization of olefins, and in particular of propylene, are capable to give polymers in high yields and with high isotactic index expressed in terms of high xylene insolubility.

  本发明涉及用于烯烃聚合的催化剂组分，以及由此获得的催化剂，特别适用于烯烃的立体聚合，该催化剂组分包括钛、镁、卤素和一种电子供体化合物，该电子供体化合物选自含丙二酸杂原子酯（含丙二酸异原子酯）。上述催化剂成分用于烯烃，特别是丙烯的聚合时，能够产生高产率和高同素异形指数（以高二甲苯不溶性表示）的聚合物。
