摘　　要：采用 2种希夫碱化合物对以n -BuLi/THF引发体系合成的溶液聚合丁二烯 -苯乙烯共聚物(SSBR)进行末端化学改性。研究结果表明 :改性后的SSBR其物理机械性能及抗湿滑性能良好 ,滚动阻力有所降低 ,说明用希夫碱化合物改性SSBR可以制备低滚动阻力橡胶。Two types of Schiff base were synthesized and used as terminators for the modification of solution polymerized styrene butadiene copolymers in this paper.It was shown that the modified SSBR had good mechanical properties,wet skid resistance and reduced rolling resistance by comparision with the ordinary SSBR and ESBR.
