我们已初步研究了在丙烯聚合络合催化剂的制备过程中,醚络合剂在络合处理步骤中的作用,它不仅可将有害于聚合的还原副产物(AlEtCl_2)络合去掉,而且可降低TiCl~3晶型的转变温度。近年来虽有关于在TiCl_4中添加醚类物质进行热处理以改善催化剂性能的报道,但都没有解释醚在其中的特殊作用。我们在催化剂制备的第三步TiCl_4溶液中添加醚(以下用(TiCl_4/醚)溶液表示)进行热处理,发现催化剂中的醚含量有明显 We have initially studied the role of the ether complexing agent in the complexation treatment step in the preparation of the propylene polymerization complex catalyst which not only can complex the reduction byproduct (AlEtCl 2) harmful to polymerization but also reduce TiCl ~ 3 crystal transition temperature. In recent years, although there are reports on the addition of ethers in TiCl 4 for heat treatment to improve the performance of catalysts, none of them explain the special effect of ethers. We in the catalyst preparation TiCl_4 solution was added ether (hereinafter used (TiCl_4 / ether) solution) heat treatment and found that the catalyst in the ether content significantly
