中文摘要: |
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,以THF为结构调节剂合成的SSBR动态性能最好。 |
英文摘要: |
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. |
