摘　　要：文章研究高结合苯乙烯SBR1721的基本性能,并将其与SBR1712进行对比研究。研究结果表明,高结合苯乙烯SBR1721的定伸应力和拉伸强度值较高,且永久变形较大,撕裂强度值较低,压缩生热较高等。SBR1721的弹性模量和损耗模量高,损耗因子随温度变化较大。The basic properties of SBR1721 combined with high styrene is researched, and compared to SBRI712. The results show that, the tensile stress, tensile strength and the set of SBR1721 is bigger, the tear strength is low, the heat generating is higher. The storage modulus and the loss modulus of SBR1721 is higher, loss factor is bigger with temperature change.
