    • Components of catalysts for polymerizing olefins are obtained by grinding together an anhydrous magnesium halide, an ester of an aromatic carboxylic acid and a silicon compound having alkenyl groups and alkoxy groups bound to the silicon atom, of the type of vinyl-triethoxy-silane, and by successively reacting the ground product with a halogenated titanium compound, liquid under the reaction conditions, such as TiCl.sub.4.The present invention provides not only the aforesaid catalyst components for the polymerization of olefins, but also catalysts obtained therefrom and the use of the same, particularly in the polymerization of the alpha-olefins CH.sub.2 .dbd.CHR wherein R is an alkyl or aryl radical with from 1 to 8 carbon atoms.In the case of the polymerization of alpha-olefins, the catalytic components, when mixed with organometallic aluminum compounds, yield final catalysts which result in an increase in the polymer yield without lowering the isotacticity index of the polymer.
    • 用于聚合烯烃的催化剂的组分通过将无水卤化镁,芳族羧酸的酯和具有烯基的硅化合物和与硅原子结合的烷氧基的乙烯基 - 三乙氧基硅烷类型,以及 通过在诸如TiCl 4的反应条件下将研磨产物与卤化钛化合物,液体连续反应。 本发明不仅提供上述用于烯烃聚合的催化剂组分,还提供了由其获得的催化剂及其用途,特别是在α-烯烃CH 2 = CHR的聚合中,其中R是烷基或芳基, 1至8个碳原子。 在α-烯烃聚合的情况下,当与有机金属铝化合物混合时,催化组分产生最终的催化剂,导致聚合物产率的增加而不降低聚合物的全同立构规整度指数。
