摘　　要：ＴｉＣｌ_４／ＳｉＯ_２－ＭｇＣｌ_２载体催化剂下的乙烯／己烯－１共聚反应陈辉，张学全，黄葆同王展望，杨永然（中国科学院长春应用化学研究所长春１３００２２）（辽阳化纤公司化工三厂辽阳）关键词乙烯，己烯，共聚，Ｚｉｅｇｌｅｒ－Ｎａｔｔａ催化剂乙烯／α－烯?..Copolymerization of ethylene/hexene-1 has been carried out by using a TiCl_4/SiO_2-MgCl_2 catalyst. Results show that the rate of copolymerization is higher than that of ethylene homopolymerization. The phenomenon is explained from the viewpoint of unsteady diffusion kinetics of heterogeneous Ziegler-Natta catalysts. The density of ethylene/hexene-1 copolymer obtained reaches the range of very low density polyethylene. The thermal behavior and sequence length distribution of copolymers have been characterized by DSC and ￣(13)C NMR.
