| 中文摘要: |
| 探讨国产溶聚丁苯橡胶（SSBR）T2530的基本性能。结果表明，与乳聚丁苯橡胶（ESBR）1712E和1712相比，SSBR生胶的重均相对分子质量略小，数均相对分子质量稍大，相对分子质量分布较窄，纯胶含量较高；混炼胶的门尼粘度较高，硫化速度较快，焦烧时间略有缩短，但加工工艺性能差别不大；硫化胶的300%定伸应力和拉伸强度略低（适当调整炭黑用量可使300%定伸应力达到ESBR的水平），弹性较好，滚动阻力较低。 |
| 英文摘要: |
| The basic properties of domestic SSBR T2530 were investigated.The results showed that when compared to ESBR1712E and 1712，SSBR T2530 possessed smaller weight-average molecular weight（Mw），greater number-average molecular weight（Mn），narrower molecular weight distribution，and higher content of SSBR；its mix also possessed higher Mooney viscosity and vulcanization rate，shorter scorch time，and similar processing properties；its vulcanizate showed lower stress at 300% strain and tensile strength （but stress at 300% strain could be enhanced to the level of ESBR by adjusting the proportion of carbon black），better elasticity，and lower rolling resistance. |
