The grafting effect and mechanism was charac- terized by FTIR,The heat stability of unvulcanized and dynamical mechanical proper- ty of vulc- lcanizates of SBR and SBR-g- were tested by TG and DMA respectively. medium-resistance properties of SBR and SBR-g- vulcan- izates were also investigated.The results showed that addition of St accelerated GMA grafting onto SBR and control the decomposition of SBR. When the conditions were GMA/St/DCP was 8/4/0.3 and grafting temperature was 160℃.

结果表明，St对提高接枝率、抑制SBR的降解起到了积极的作用；SBR中聚丁二烯的α－H和双键共同参与了GMA/St熔融接枝反应；当SBR/GMA/St/DCP=100/8/4/0.3、接枝温度为160℃时，SBR的接枝率较高（23.78%），SBR–g–硫化胶的拉伸强度和撕裂强度比SBR硫化胶的分别提高了119%和27.4%；SBR–（GMA--co-St）未硫化胶的Tg比SBR未硫化胶的高，而耐热分解性能优于SBR未硫化胶；SBR–g–硫化胶在低温条件下的刚性增大、弹性降低、具有较低的内耗，在常温下的阻尼性能较高，但弹性性能保持较好；SBR–g–硫化胶的耐热稳定性以及耐非极性有机溶剂的性能优于SBR硫化胶。
