摘　　要：采用阴离子聚合法合成了端羟基聚丁二烯,通过端基转化法将羟基转化成胺基,从而合成了端胺基聚丁二烯,通过红外光谱(IR)、核磁共振(1H-NMR)、凝胶渗透色谱(GPC)等对其进行了表征。结果表明,所合成的端胺基聚丁二烯相对分子质量分布较窄(≤1.10),平均官能度接近2,且微观结构可调;通过羟基值与胺基值的测定表明,端基转化率大于98%。Hydroxyl-terminated polybutadiene has been synthesized via anionic polymerization.Amino-terminated polybutadiene was synthesized by converting hydroxyl terminal groups to amino terminal groups.The polymers were characterized by using IR,1H-NMR,GPC and so on.The results showed that the polymers have low molecular weight distribution below or equal to 1.10,functionality approach 2,and the microstructure can be controlled.By analyzing hydroxyl value and amine value,the results showed that the converting ratio of hydroxyl groups to amine groups is greater than 98%.
