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℃.
