    • This invention comprises a catalytic component for polymerizing olefins comprising a solid support containing magnesium-halogen bonds, a transition metal halide of a metal selected from Groups IVB and VB of the periodic table, and an electron donor obtained by the steps comprising:

      (a) reacting an organometallic compound whose metal comprise members of Groups I to III of the periodic table with an alcohol, ROH, where R is an alkyl, cycloalkyl, or arylalkyl moiety having 1 to 16 carbon atoms, a polysiloxane, and a transition metal halide to form a solid;
      (b) treating the solid with a transition metal halide optionally int he presence of a polysiloxane to form a treated solid; and
      (c) reacting the treated solid with an electron donor and a transition metal halide to form the component.
    • 本发明包括用于聚合烯烃的催化组分,其包含含有镁 - 卤键的固体载体,选自元素周期表第IVB和VB族的金属的过渡金属卤化物和通过以下步骤获得的电子供体:(a) 使其金属包含元素周期表第I至III族成员的有机金属化合物与醇ROH(其中R为具有1至16个碳原子的烷基,环烷基或芳烷基部分),聚硅氧烷和过渡金属卤化物反应以 形成坚实的; (b)任选在聚硅氧烷存在下用过渡金属卤化物处理固体以形成处理的固体; 和(c)使处理过的固体与电子供体和过渡金属卤化物反应以形成组分。
