| Abstract: |
| The processibility，physical properties and dynamic heat build-up of Sn-coupled S-SBR/BR blend were investigated. The results showed that the Mooney viscosity of Sn-coupled S-SBR with proper level of homogenizing agent was similar to that of BR；the flexibility，abrasion resistance and heat build-up of the blend improved，and its tensile strength decreased as the proportion of BR increased；the optimal balanced physical properties of the vulcanizate were obtained when the Sn-coupled S-SBR/BR with the blending ratio of 60/40 and the CB N234 were used. |
