摘　　要：研究结构调节剂四氢呋喃 (THF)、二乙二醇二甲醚 ( 2G)和N ,N ,N′ ,N′ 四甲基乙烯基二胺 (TMEDA)对溶聚丁苯橡胶 (SSBR)结构和性能的影响。试验结果表明 ,随结构调节剂用量的增大和反应温度的降低 ,SSBR中 1,2 结构质量分数增大 ;随结构调节剂用量的增大 ,SSBR中苯乙烯结构质量分数逐渐接近苯乙烯与丁二烯的投料比 ;结构调节剂品种对SSBR物理性能影响不大 。The influence of various structure modifiers,such as THF,2G and TMEDA,on the microstructure and properties of SSBR was investigated.The test results showed that 1,2-content in SSBR increased as the modifier concentration increased and the reaction temperature decreased;the styrene content in SSBR closed gradually to the charge ratio of styrene/butadiene as the modifier concentration increased;and the type of structure modifier had little effect on the physical properties of SSBR,but THF gave the best dynamic properties to SSBR vulcanizates.
