摘 要:采用GC-MS和13C NMR對Ziegler-Natta催化劑催化1-癸烯齊聚所得齊聚物的組成和結構進(jìn)行了表征。GC-MS和GC的分析結果表明所得齊聚物是混合物,主要由二聚體、三聚體、四聚體和五聚體組成。齊聚物的質(zhì)量百分含量分別為14%、45%、31%和10%。13C NMR結果表明1-癸烯齊聚時(shí)存在鍵接異構,除頭-尾鍵接的1,2插入,還存在頭-頭,尾-尾鍵接的2,1插入。1-癸烯齊聚物的傾點(diǎn)低,粘度指數高。

Structure and Properties of Oligomer from 1-Decene Catalyzed by Ziegler-Natta Catalyst
YANG Xiao-yu(Hunan Chemical Industry Profession and Technology College; Zhuzhou 412004; China)
Abstract:The oligomer from 1-decene promoted by Ziegler-Natta Catalyst was characterized with GC-MS,GC and 13C NMR methods.The results from GC-MS and GC analysis confirmed that the oligomer was a mixture consisting of di-(14%),tri-(45%),tetra-(31%) and pentamer(10%).The 13C NMR data also implied that the chain propagation of the oligomer involved primarily head-to-tail 1,2-insertions,as well as head-to-head and tail-to-tail 2,1-insertions.The oligomer obtained featured lower pour point and high viscosity index.
