Disclosed are catalyst components for the polymerization of olefins comprising magnesium halide in active form, and, supported thereon, a titanium halide or titanium halogen alcoholate and an electron-donor compound selected from the diamines of formula
wherein the radicals R1 to R1 0 are the same or different and are hydrogen or C1 -C1 8 hydrocarbon radicals, with the proviso that at least one of the R7 and R8 radicals and at least one of the R9 and R10 radicals are not hydrogen. Also, disclosed are catalysts obtained from said catalyst components and an AI-alkyl compound, as well as catalysts obtained by reaction of an AI-alkyl compound and a diamine of formula (I) with a solid catalyst component comprising a titanium halide or a titanium halogen alcoholate, and an electron-donor compound having particular characteristics of extractability with AI-triethyl, supported on magnesium halide in active form.
公开了用于烯烃聚合的催化剂组分,该组分包括活性形式的卤化镁,以及支撑在其上的卤化钛或卤代醇酸钛和选自式二胺的电子供体化合物。
其中 R1 至 R1 0 的基是相同或不同的,并且是氢或 C1 -C1 8 烃基,但 R7 和 R8 中至少有一个基以及 R9 和 R10 中至少有一个基不是氢。此外,还公开了由上述催化剂组分和 AI-烷基化合物得到的催化剂,以及由 AI-烷基化合物和式 (I) 二胺与固体催化剂组分反应得到的催化剂,固体催化剂组分包括卤化钛或卤化钛醇酸酯,以及具有与 AI-三乙基可萃取性特殊性质的电子供体化合物,以活性形式支撑在卤化镁上。
