中国石油化工股份有限公司开发出一种超高分子量聚乙烯催化剂及其制备方法。该超高分子量聚乙烯催化剂先由卤化镁与烃类溶剂反应,再加入醇化合物,与卤化镁化合物形成醇镁化合物,再依次加入给电子体Ⅰ、卤代烷基铝、给电子体Ⅱ最后生成中间产物,对中间产物进行超声波处理后,加入钛化合物进行载钛反应,最
China Petroleum & Chemical Corporation developed an ultra-high molecular weight polyethylene catalyst and its preparation method. The ultrahigh-molecular-weight polyethylene catalyst is prepared by reacting magnesium halide with a hydrocarbon solvent, adding an alcohol compound, forming a magnesium alkoxide compound with the magnesium halide compound, and sequentially adding the electron donor I, the aluminum alkyl halide and the electron donor II to finally form an intermediate The product, the intermediate product after ultrasonic treatment, adding a titanium compound carrying titanium reaction, the most
