摘　　要：用双酚A型环氧树脂(E-51)和2-丙烯酰胺基-2-甲基丙磺酸(AMPS)合成了可用于紫外光固化的双酚A型环氧磺酸酯(AMPS-EP)。研究了影响反应的多种因素,优化的合成条件为:以N,N-二甲基甲酰胺(DMF)为溶剂,AMPS与E-51的摩尔投料比为1∶0.5,对苯二酚为阻聚剂,用量为环氧树脂质量的0.2%,反应时间5 h,反应温度70℃。反应程度的测定和产物结构表征结果表明:环氧基团与磺酸基团酯化率在93%以上,AMPS-EP保留了约82%的丙烯酰胺基团,玻璃化转变温度为57℃。在反应温度范围内推测反应为一级反应,反应的表观活化能为9.76 kJ/mol。Bisphenol A epoxy sulphonate（AMPS-EP） has been synthesized by using 2-acrylamido-2-methyl-propanesulfonic acid（AMPS） and bisphenol A-type epoxy resin（EP）.A variety of factors of the reaction were investigated and the optimum condition was determined.The optimum conditions：N,N-dimethylformamide（DMF） as solvent,the molar ratio of AMPS and epoxy materials is 1∶0.5,hydroquinone as inhibitor,amount of 0.2%（wt） of EP,reaction time 5 h,reaction temperature 70℃.The products were characterized by FT-IR and DSC.The results show more 93% of epoxy groups and sulfonic groups took part in the reaction,about 82% of acrylamide groups retained finally and the glass transition temperature of AMPS-EP was 57℃.At the range of reaction temperature,the progression of the reaction was one;the apparent activation energy was 9.76 kJ/mol.
