| 摘 要： | 采用新型稀土催化体系氯代三氟乙酸钕－烷基铝－卤代烃，引发苯乙烯均聚及其与异戊二烯共聚。 催化体系各组分及陈化方式、Ｘ和Ａｌ种及用量，溶剂种类等因素对苯乙烯聚合的影响，并用稀土催化实现了Ｓｔ－Ｉｐ嵌段共聚。用ＩＲ，ＮＭＲ及ＤＳＣ等方法表征了聚合物的结构，合成出的Ｓｔ－Ｉｐ二嵌段共聚物中，Ｉｐ链节以反式－１，４－结构为主，含少量３，４－结构，几科不含顺式－１，４－结构。

| Abstract: | Styrene (St)homopolymerization and copolymerization with isoprene (Ip) initiated by a novel catalyst system(CF3COO)2 NdCl-Me3Al-allyl Br.The effect of components,aging matter, third components,aluminum alkyls and solvents on the polymerization of styrene were studied.Then the block copolymer of St and Ip was carried out successfully.The alleged polymer was characterized by IR,NMR and DSC.The Ip unit of St-Ip block copolymer was dominated by the trans-1,4-structure and few 3,4-structure without any cis-1,4-structure. |
