摘　　要：对用高活性引发体系在较短聚合周期（９—１１ｈ）内合成的高转化率（７％）Ｅ－ＳＢＲ１５００生胶的门尼粘度、凝胶含量、结合苯乙烯含量、分子量分布、组成分布和微观结构等基本特性参数和硫化胶的物性进行了试验研究。结果表明：生胶的各项特性指标和硫化胶物性均达到了６０％转化率的我国吉化和日本ＪＳＲ胶样的实测值水平。The properties of high-conversion E-SBR 1500 synthesized with PMHP-SFS-EDTA·FeNa redox system in a shorter polymerization cycle were studied. The results showed that E-SBR 1500 was comparable with JSR(Japan)and Jihua (China)products in terms of properties, such as Mooney viscosity,gel content, bound styrene content, molecular weight distribution, composition profiles and micro-structure,as well as the properties of its vulcanizate.
