    • PURPOSE: A method for preparing a Ziegler-Natta catalyst for olefin polymerization is provided to reduce the used amount of expensive titanium due to high activity and high steric regularity and to prepare a polymer having wide molecular weight distribution. CONSTITUTION: A method for preparing a Ziegler-Natta catalyst for olefin polymerization comprises the steps of: (i) dissolving anhydrous magnesium halide in anhydrous alcohol and hydrocarbon solvents and adding a precipitation accelerator to prepare a magnesium carrier mixture solution; (ii) adding transition metal compounds to the magnesium carrier mixture solution to obtain precipitates; and (iii) washing the precipitates with the hydrocarbon solvent, adding transition metal compounds, washing the added mixture with the hydrocarbon solvent, to obtain a solid catalyst.
    • 目的:提供一种制备用于烯烃聚合的齐格勒 - 纳塔催化剂的方法,以降低由于高活性和高立体规则性而导致的昂贵钛的使用量,并制备具有宽分子量分布的聚合物。 构成:用于制备用于烯烃聚合的齐格勒 - 纳塔催化剂的方法包括以下步骤:(i)将无水卤化镁溶解在无水乙醇和烃溶剂中并加入沉淀促进剂以制备镁载体混合物溶液; (ii)向镁载体混合溶液中加入过渡金属化合物,得到沉淀物; 和(iii)用烃溶剂洗涤沉淀物,加入过渡金属化合物,用烃溶剂洗涤加入的混合物,得到固体催化剂。
