中文摘要:
      研究中国石油独山子石化公司溶聚丁苯橡胶（SSBR）SOL RC 2557-A的微观结构、相对分子质量及其分布、硫化特性、物理性能和动态力学性能。结果表明：与国外SSBR 5025-2相比，SSBR SOL RC2557-A的相对分子质量分布略窄，物理性能、耐老化性能和抗湿滑性较好，滚动阻力较小。
英文摘要:
      The microstructure，molecular weight and molecular weight distribution，curing characteristics，physical properties and dynamic mechanical properties of the solution polymerized styrene-butadiene rubber（SSBR），SOL RC2557-A，from PetroChina Dushanzi Petrochemical Company，were investigated. The resultsshowed that，compared with SSBR 5025-2 which was supplied by a foreign company，the molecular weightdistribution of SOL RC2557-A was slightly narrower，the physical properties，aging resistance and wet skidresistance were better， and therolling resistance was lower.
