| 中文摘要: |
| 采用自制环醚调节剂（调节剂T），以正丁基锂为引发剂，以环己烷-己烷为溶剂，采用阴离子聚合法合成高乙烯基溶聚丁苯橡胶（SSBR），并对其性能进行研究。结果表明，调节剂T具有较好的乙烯基含量调节能力，在用量较小的情况下即可合成高乙烯基SSBR；与中低乙烯基SSBR相比，高乙烯基SSBR具有良好的物理性能、优异的抗湿滑性能和较低的滚动阻力及生热。 |
| 英文摘要: |
| Using the n-butyllithium as initiator，self-made cyclic ether modifier(modifier T)，cyclohexane and hexane mixed solvent，the high-vinyl solution-polymerized styrene-butadiene rubber(SSBR) was prepared by anonic solution copolymerization，and its properties were investigated.The results showed that，modifier T gave good control of vinyl content in SSBR，and the high vinyl SSBR could be synthesized with low dosage of modifier T；the high-vinyl SSBR had good physical properties，excellent wet skid resistance，lower rolling resistance and heat build-up. |
