| 中文摘要: |
| 研究低顺式聚丁二烯橡胶（LCBR）在高用量白炭黑胎面胶中的应用。结果表明：与高顺式聚丁二烯橡胶（BR9000）相比，LCBR的微观结构明显不同，玻璃化温度升高12 ℃；LCBR等量替代BR9000后，胶料的门尼粘度略有升高，加工性能略差，物理性能基本相当，动态力学性能明显提升，滚动阻力降低。 |
| 英文摘要: |
| The application of low cis-polybutadiene rubber（LCBR） in tread compound with high dosage silica was studied.The results showed that，compared with high cis-polybutadiene rubber（BR9000），the microstructure of LCBR was significantly different，with a glass transition temperature increase of 12 ℃.After replacing BR9000 with LCBR，the Mooney viscosity of compound slightly increased，the processing performance was slightly worse，the physical properties were basically equivalent，and the dynamic mechanical properties were significantly improved. |
