| 摘 要： | 研究了以ＳｉＯ２为载体的Ｍｅ２Ｓｉ（Ｉｎｄ）２ＺｒＣｌ２／ＭＡＯ催化乙烯－己烯共聚合反应。在试验条件下，随着共聚单体己烯含量的增加，共聚物相对分子质量、熔点和密度均下降；反应活性则呈现共单体效应。研究了该共聚物序列结构、组成、数均链长，测定了该共聚物的竞聚率ｒ１＝１３．６、ｒ２＝０．０７４、ｒ１ｒ２＝１．０。

| Abstract: | The copolymerization of ethylene and hexene with silica supported Me 2Si(Ind) 2ZrCl 2 was investigated The molecular weight,melting point and density of the copolymer decreased with increasing molar ratio of H / E ,and the “comonomer effect”was observed for reactivity The composition,sequence distribution,number average chain length and reactivity ratio were determined |
