    • Catalyst-forming components are prepared from(a) a halogenated Ti compound containing at least a Ti-halogen bond;(b) an electron-donor compound free of active hydrogen atoms;and(c) the solid product of the reaction between at least one electron-donor compound containing active hydrogen atoms and a Mg dihalide or a complex thereof with an electron-donor compound free of active hydrogen atoms, obtained by decomposing organic Mg compounds containing at least one Mg-R or Mg-OR group, in which R is an alkyl, aryl, cycloalkyl or alkenyl radical having 1 to 20 carbon atoms, by means of a halogenating agent different from (a).Catalysts for polymerizing olefins and prepared by mixing the aforesaid catalyst-forming components with an organometallic compound of Al are also disclosed.
    • 催化剂形成成分由(a)至少含有Ti-卤素键的卤化Ti化合物制备; (b)不含活性氢原子的电子给体化合物; 和(c)包含活性氢原子的至少一种电子给体化合物与二卤化镁或其配合物与不含活性氢原子的电子给体化合物之间的反应的固体产物,通过分解含有 至少一个Mg-R或Mg-OR基团,其中R是具有1至20个碳原子的烷基,芳基,环烷基或烯基,通过不同于(a)的卤化剂。 还公开了用于聚合烯烃并通过将上述催化剂形成组分与Al的有机金属化合物混合制备的催化剂。
