| 中文摘要: |
| 对充油溶聚丁苯橡胶（SSBR）和乳聚丁苯橡胶（ESBR）的结构和性能进行对比研究。结果表明：充油SSBR与ESBR的微观结构相差较大，SSBR的1，2-结构和顺式-1，4-结构质量分数较大，相对分子质量分布较窄，滞后损失小；SSBR HP755R硫化胶具有良好的物理性能、耐磨性能、抗湿滑性能和较低的滚动阻力，SSBR HP755R适用于轮胎胎面胶；SSBR2564S硫化胶的物理性能和抗湿滑性能略差于、滚动阻力略高于SSBR HP755R硫化胶。 |
| 英文摘要: |
| The structure and properties of oil-extended solution-polymerized styrene-butadiene rubber（SSBR）and emulsion-polymerized styrene-butadiene rubber（ESBR） were studied.The results showed that the microstructures of SSBR and ESBR were quite different.SSBR had large mass fraction of 1，2-structure and cis-1，4-structure，relatively narrow molecular weight distribution，and small hysteresis loss.SSBR HP755R vulcanizates had good physical properties，wear resistance，wet skid resistance and low rolling resistance，which was suitable for tire tread compound.The physical properties and wet skid resistance of SSBR2564S vulcanizates were slightly worse than that of SSBR HP755R vulcanizates，and rolling resistance was slightly high. |
