Abstract:
      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.
