%X 研究高乙烯基溶聚丁苯橡胶（SSBR）C2557A的结构和性能，并与乳聚丁苯橡胶（ESBR）1712和SSBR-T2530进行对比。结果表明：与ESBR-1712和SSBR-T2530相比，SSBR-C2557A的数均相对分子质量最大，相对分子质量分布指数介于两者之间，而其链结构中乙烯基质量分数较高。SSBR-C2557A硫化胶的高弹态动态模量较大，玻璃化温度在0 ℃附近，其抗湿滑性能优于ESBR-1712和SSBR-T2530，但损耗因子和压缩疲劳温升较高。;The structure and properties of high-vinyl solution-polymerized SBR（SSBR） C2557A were investigated，and compared with those of emulsion-polymerized SBR（ESBR） 1712 and SSBR-T2530.The results showed that，compared with ESBR-1712 and SSBR-T2530，SSBR-C2557A possessed higher vinyl content and larger number-average relative molecular weight，and its relative molecular weight distribution index ranged between those of ESBR-1712 and SSBR-T2530.The vulcanizates of SSBR-C2557A possessed higher dynamic modulus at large elastic state and the glass transition temperature close to 0 ℃.The wet skid resistance of SSBR-C2557A vulcanizates was better than that of ESBR-1712 and SSBR-T2530，but the loss factor and compression fatigue temperature rise were higher
