摘要

用均相茂金属催化剂(n-Bu)Cp2ZrCl2/MAO对1-癸烯的齐聚合进行了研究。探讨了齐聚温度、Al/Zr摩尔比值、助催化剂、反应时间及催化剂浓度对齐聚反应的影响。采用GC-MS、GC和13C NMR对齐聚物的组成和结构进行了表征。GC-MS和GC的分析结果表明所得齐聚物是由二聚体、三聚体、四聚体和五聚体组成。13C NMR分析结果表明1-癸烯齐聚时存在键接异构，主要是头-尾键接的1，2插入，也存在头-头、尾-尾键接的2，1插入。

Abstract

The synthesis of oligomer from 1-decene with metallocene catalyst(n-Bu)Cp2ZrCl2/MAO was studied.The effects of temperature

Al/Zr ratio

time and concentration of the catalyst on oligomerization behavior were investigated.The oligomer obtained was characterized with GC-MS

GC and 13C NMR.Those results confirmed that the oligomer was a mixture consisting of di-

tri-

tetra- and pentamer.The 13C NMR data also implied that chain propagation of the oligomer involved primarily head-to-tail 1

2-insertions

as well as head-to- head

tail-to-tail

1-insertions.
