| 中文摘要: |
| 以自制路易斯碱为调节剂（调节剂T）、正丁基锂为引发剂，采用阴离子聚合法、填充环保型芳烃油RAE制备环保型高乙烯基溶聚丁苯橡胶（HVSBR），并对比研究了几种胎面用丁苯橡胶与顺丁橡胶（BR）并用胶的性能。结果表明：少量的调节剂T有助于合成相对分子质量分布宽、加工性能好的HVSBR，乙烯基质量分数可达0.6～0.7；HVSBR/BR并用胶的综合物理性能、耐磨性能和动态力学性能较好，压缩疲劳温升和永久变形较小。 |
| 英文摘要: |
| Using self-made Lewis base as modifier(modifier T) and n-butyllithium as initiator，the high-vinyl solution styrene butadiene rubber(HVSBR) was prepared by anionic solution copolymerization.HVSBR was filled with environment-friendly oil RAE， and the properties of several SBR/BR blends for tire tread were comparatively investigated.The results showed that，small addition level of modifier T helped to produce HVSBR with wide relative molecular weight distribution and good processability，and the mass fraction of vinyl content could reach 0.6～0.7.The comprehensive physical properties，wear resistance and dynamic properties of HVSBR/BR blend were better，and compression fatigue heat build-up and compression set were lower. |
