    • A method of making a solid procatalyst composition for use in a Ziegler-Natta olefin polymerization catalyst composition, said method comprising: contacting a precursor composition comprising a magnesium compound with a titanium halide compound and an internal electron donor in any order, in a suitable reaction medium to prepare a solid procatalyst composition, separating the solid procatalyst from the reaction medium, extracting the solid procatalyst composition by contacting the same one or more times with a liquid diluent at an elevated temperature for a period of time sufficient to prepare a solid procatalyst composition having a decreased titanium content compared to the titanium content of the solid procatalyst composition before said extraction, and recovering the solid procatalyst composition.
    • 一种制备用于齐格勒 - 纳塔烯烃聚合催化剂组合物的固体前催化剂组合物的方法,所述方法包括:在合适的反应中以任何顺序将包含镁化合物的前体组合物与卤化钛化合物和内部电子给体接触 培养基以制备固体前催化剂组合物,将固体前催化剂从反应介质中分离出来,通过在高温下将液体稀释剂与液体稀释剂接触一段或者多次,将其固体原料催化剂组合物提取一段时间足以制备固体前催化剂组合物 在所述萃取之前,与固体前催化剂组合物的钛含量相比,钛含量降低,并且回收固体前催化剂组合物。
