中文摘要:
      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。
英文摘要:
      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.
