摘要： 以环己烷为溶剂, 浓硫酸和丙酸酐为磺化剂, 采用非均相磺化方法, 在少量分散剂作用下, 制备了不同磺化度的磺化聚苯乙烯(S sPSH);再以 SsPSH 和环氧树脂经加成、取代合成了梳型聚苯乙烯环氧苯醚, 最后加入固化剂制得聚苯乙烯环氧醚聚氨酯。 反应的最佳原料配比为:n(S sPSH )∶n(EP)∶n(固化剂)∶n(催化剂) =1. 0∶1.0∶0. 33∶0.012, 各过程产品经 FT - IR、TG、DTG、DTA、DSC、DMA 检测, 结果表明目标产品韧性好、强度高、耐热性好。

Abstract: A sulfona tedpoly styrene (SsPSH)was prepa redin cyclohexanewith propionic anhydride and sulfuricacid by anovel solid - liquidhe terogeneous phase su lphonation process.Then a kind of comb -polystyrene epoxy - etherwas attained by the addition and substitu tion between epoxy resin and sulfonated polystyrene. Eventually, curing agents w ere added to get po lysty rene epoxy - ether polyu re thane. The optimized process conditions are n(SsPSH)∶n(EP)∶n(solid - liquid)∶n(catalyst) =1.0∶1.0∶0.33∶0.012. All reaction products were characte rized by FT - IR,TG,DTA,DTG,DSC,DMA.Experimentalresults show that the target film has good tenacity, tensil streng th and high thermostability
