摘　　要：用溶液法由液体端羧基聚丁二烯（ＣＴＰＢ）及液体端羧基聚（丁二烯－ｃｏ－丙烯腈）（ＣＴＢＮ）合成了Ｌｉ＋、Ｎａ＋、Ｋ＋、Ｍｇ２＋、Ｚｎ２＋、Ａｌ３＋的遥爪型离聚体．考察了反应条件对离聚体形成的影响及离聚体稀溶液的性质。并用红外光谱，透射电子显微镜、动态粘弹谱仪研究和表征了部分ＣＴＰＢ、ＣＴＢＮ遥爪型离聚体．he ionomers of a,co-carboxylato-polybutadiene and α,ω-carboxylate poly (butadieneco-acrylonitrile) with Li+, Na+, K+, Mg2+, Zn2+, A13+ were prepared in toluene. Both the absolute viscosity of the concentrated solution and relative viscosity of the dilute solution of these ionomers were investigated. The ionomers were characterized by infrared spectroscopy, transmission electron microscope, and dynamic mechanical analysis. The results showed that: 1) the maximum absolute viscosity of the ionomer solutions of α, ω-carboxylato-polybutadiene and α, ω-carboxylate poly (butadiene-co-acrylonitrile) with different metal ions were related to the species of metal ions and the molar ratio of M/-COOH, 2) there were sharp increases in the relative viscosity of the ionomer solutions with increasing concentrations, which were caused by the formation of the ion-cluster in the solutions, 3) the size of the ion-cluster in the ionomers containing different metal ions depended on the species of the metal ions.
