摘要
研究了聚苯乙烯 -聚异戊二烯 -聚苯乙烯三嵌段共聚物 (SIS )在不同溶剂中的环氧化反应。SIS在甲苯溶剂中的反应速度较快 ,但副反应较多 ;在环己烷溶剂中反应速度较慢 ,但副反应较少。SIS环氧化反应比较适宜的溶剂为甲苯和环己烷的混合溶剂。
The epoxidation of styrene-isoprene block copolymer (SIS) in different organic solvents was studied.The reactive rate of epoxidation of SIS in toluene was faster than it was in cyclohexane,and side reaction in toluene was little than it in cyclohexane.Toluene/cyclohexane was more favorable than cyclohexane or toluene.
