| 摘 要： | 研究了锡偶联型溶聚丁苯橡胶（SSBR）生胶及其混炼胶的流变性能。并与乳聚丁苯橡胶（ESBR）作了对比。结果表明，锡偶联型SSBR生胶及混炼胶均属切力变稀的假塑性流体，混炼胶对剪切速率和温度的敏感性比生胶强。SSBR混炼胶对剪切速度的敏感性比ESBR混炼胶的强。挤出胀大效应表明锡偶联型SSBR混炼胶的弛豫速度比ESBR混炼胶的快，挤出胀大小，加工性能优于ESBR。

| Abstract: | The rheological properties of Sn-coupled SSBR raw and compound were studied and compared with ESBR. The result showed that both the raw and compound of Sn-coupled SSBR were pseudo-plastic fluid with shear stress, Sn-coupled SSBR compound was more sensible to shear rate and temperature than Sn-coupled SSBR raw,and was more sensible to shear rate than ESBR. Die swell of extrudate indicated that the relaxation rate of Sn-coupled SSBR compound was faster and the die swell was less obvious than that of ESBR. |
