摘　　要：以端羧基液体丁腈橡胶(CTBN)和环氧树脂(ER)为原料,三苯基膦作为催化剂,在真空密封条件下制备了ER-CTBN聚合物。运用FT-IR、1 H-NMR、GPC和TGA等方法表征了聚合物的结构。结果表明,环氧树脂的环氧基团开环和CTBN中的-COOH发生反应生成酯键,形成了一种新的聚合物,并阐明了聚合反应的反应历程。此聚合物能被作为共聚甲醛(POM)和丁腈橡胶(NBR)共混的一种新型增容剂,以达到增强POM和NBR相容性的目的。Epoxy resin-liquid CTBN（ER-CTBN）copolymer was synthesized with carboxyl terminated liquid butadiene-acrylonitrile（CTBN）and epoxy resin（ER）in a vacuum sealed condition.The reaction was catalyzed by triphenylphosphine.The structure of ER-CTBN was characterized by FT-IR,1H-NMR,GPC and TGA.The results showed that the oxirane groups of ER were opened and reacted with the carboxylic groups of CTBN,which indicated the formation of functional group ester.Besides,the process of polymerization reaction was clarified.As a novel compatibilizer,this polymer is added to rubber-plastic blending,which can improve the compatability of POM and NBR.
