  The present invention relates to catalyst components for the polymerization of olefins comprising a titanium compound, having at least a Ti-halogen bond, and at least two electron donor compounds supported on a Mg dihalide, said catalyst component being characterized by the fact that at least one of the electron donor compounds is selected from ethers containing two or more ether groups which are further characterized by the formation of complexes with anhydrous magnesium dichloride in an amount less than 60 mmoles per 100 g of MgCl 2 and by the failure of entering into substitution reactions with TiCl 4 or by reacting in that way for less than 50% by moles, and at least another electron donor compound is selected from esters of mono or polycarboxylic acids. Said catalyst components are able to produce propylene polymers which, for high values of xylene insolubility, show a broad range of isotacticity.

  本发明涉及用于烯烃聚合的催化剂组分，该催化剂组分包括至少具有一个钛卤键的钛化合物和至少两种支撑在二卤化镁上的电子供体化合物，所述催化剂组分的特征是至少一种电子供体化合物选自含有两个或两个以上醚基的醚，其进一步特征是与无水二氯化镁形成的络合物的量少于每 100 克氯化镁中 60 毫摩尔。 2 以及不能与 TiCl 4 或以这种方式进行反应的摩尔数少于 50%，至少还有一种电子供体化合物选自单羧酸或多羧酸的酯类。上述催化剂组分能够生产出丙烯聚合物，在二甲苯不溶性值较高的情况下，这种聚合物具有较宽的等活度范围。
