| Abstract: |
| 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. |
