摘　　要：采用反应加工方法,以氢化钠(NaH)作活性剂、三乙基氯硅烷(Et3SiCl)作改性剂制备硅烷化改性乳聚丁苯橡胶(Si-ESBR),并对其动态性能进行研究。Si-ESBR最佳改性条件为:ESBR 50g,NaH 0.04mol,Et3SiCl 0.04mol,加入NaH后的反应时间15min,加入Et3SiCl后的反应时间15min,反应温度80℃。ESBR硅烷化改性后胶料的Payne效应明显降低,填料的网络化效应得到改善,动态能量损耗减小。The silane modified ESBR（Si-ESBR） was prepared by reaction processing method and using Nail as activating agent and Et3SiC1 as modifier, and the dynamic properties of Si-ESBR were studied. The optimum reaction condition was as follows：ESBR 50 g,NaH 0.04 mol,Et3SiCl 0.04 mol,reaction time after adding Nail 15 min, reaction time after adding Et3SiCl 15 min, reaction temperature 80℃. With the modification, the Payne effect of Si-ESBR decreased significantly, the filler network improved effectively,and the dynamic energy loss decreased.
