    • PURPOSE: A method for preparing a solid catalyst for the polymerization of propylene is provided to obtain a solid catalyst capable of polymerizing polypropylene with excellent tacticity while exhibiting high melt flow index and wide molecular weight distribution. CONSTITUTION: A method for preparing a solid catalyst for the polymerization of propylene comprises the steps of: (i) reacting dialkoxymagnesium with titanium halide in the presence of organic solvents; (ii) injecting an internal electron donor selected from chemical formula (III) and an internal electron donor selected from chemical formula (IV) into the resultant of step (i) while raising the temperature to 80~130°C; and (iii) reacting the resultant of step (ii) with titanium halide at a temperature of 80~130°C and washing the resultant.
    • 目的:提供一种制备用于丙烯聚合的固体催化剂的方法,以获得能够显示高熔体流动指数和宽分子量分布的具有优异立构规整度的聚丙烯的固体催化剂。 构成:制备用于丙烯聚合的固体催化剂的方法包括以下步骤:(i)在有机溶剂存在下使二烷氧基镁与卤化钛反应; (ii)在将温度升至80〜130℃的同时,将选自化学式(III)的内电子给体和选自化学式(IV)的内电子给体注入到步骤(i)的结果中; 和(iii)使步骤(ii)的所得物与卤化钛在80〜130℃的温度下反应并洗涤所得物。
