    • Catalysts for the polymerization of alpha-olefins, which comprise the product of the reaction between:(a) a metalorganic compound of Al;(b) an electron-donor compound reactive towards MgCl.sub.2 but which is not completely complexed with AlEt.sub.3, at the equivalent point of a potentiometric titration under standard conditions;(c) a solid comprising a halogenated Ti compound and an electron-donor belonging to particular classes of compounds and being extractable with AlEt.sub.3 for at least 70% by mols from the solid, the surface area of which after extraction is higher than 20 m.sup.2 /g.The present invention refers to new supported components of catalysts for the polymerization of olefins CH.sub.2 .dbd.CHR, in which R is an alkyl with 1-14 carbon atoms or an aryl, and of mixtures of such olefins with each other and/or with ethylene, and to the catalysts obtained from such components.
    • 用于α-烯烃聚合的催化剂,其包括以下反应的产物:(a)Al的金属有机化合物; (b)在标准条件下在电位滴定的等效点处,与MgCl 2反应但不与AlEt3完全络合的电子给体化合物; (c)包含卤化Ti化合物和属于特定类别化合物的电子给体的固体,并且可与AlEt3一起从固体中提取至少70%的摩尔数,其提取后的表面积高于20m 2 / G。 本发明涉及用于烯烃CH 2 = CHR(其中R是具有1-14个碳原子的烷基或芳基)和这些烯烃与彼此和/或与乙烯的混合物的聚合的催化剂的新的负载组分, 和由这些组分获得的催化剂。
