中文摘要:
      以不同牌号溶聚丁苯橡胶（SSBR）为研究对象，考察SSBR的耐疲劳性能与其微观结构之间的相关性。结果表明：SSBR的耐疲劳破坏性能随着苯乙烯含量、乙烯基含量和填充油量的增大而提高，随着嵌段苯乙烯含量的增大而降低；SSBR的玻璃化温度越接近实际使用温度，其疲劳寿命越高；SSBR的耐疲劳性能与其交联密度和耐老化性能相关性显著，交联密度越低、耐老化性能越高，则SSBR的耐疲劳性能越高。
英文摘要:
      The correlation between fatigue resistance and micro-structure of SSBR was studied based on different grades of SSBR.The results showed that，the flex fatigue life was extended with increase of bound styrene content，vinyl content and extending oil amount，while it was reduced with increase of block styrene content.The compound showed better fatigue life when its glass transition temperature was close to the operating temperature.It was found that the fatigue life of SSBR was significantly correlated with its crosslink density and aging resistance，and the fatigue life increased with decrease of crosslink density and improvement of aging resistance.
