中文摘要:
      分别将不同微观结构的溶聚丁苯橡胶（SSBR）与顺丁橡胶（BR）并用，研究SSBR的微观结构对SSBR/BR并用胶性能的影响。结果表明：在一定范围内，随着苯乙基含量的增大，SSBR/BR硫化胶的拉伸强度呈增大趋势，回弹值与切割量之间具有较好的线性相关性；高苯乙烯基和中低乙烯基含量的SSBR/BR并用胶的t90较短，最大硫化速率较大，硫化胶的抗湿滑性能和耐磨耗性能较高，同时滚动阻力较低。
英文摘要:
      Solution polymerized styrene butadiene rubber（SSBR） with different microstructures and butadiene rubber（BR） were blended separately，and the effect of SSBR microstructure on the properties of SSBR/BR blends was investigated. The results showed that in a certain range，with the increased of phenethyl content，the tensile strength of SSBR/BR vulcanizate trended to increased，and there was a good linear correlation between rebound value and cutting amount. The t90 of the high styrene and low to medium vinyl content SSBR/BR blends was shorter，the maximum vulcanization rate was higher，the wet skid resistance and wear resistance of the vulcanizate were higher，while the rolling resistance was lower.
