摘　　要：以对甲苯磺酸为催化剂,对羟基苯甲醚为阻聚剂,甲苯为共沸脱水剂,FEVE树脂和丙烯酸为原料,通过FEVE树脂的羟基与丙烯酸发生酯化反应制备了含氟光固化树脂。讨论了羧基与羟基摩尔比、催化剂用量、共沸脱水剂用量和反应时间对酯化反应转化率的影响。通过FT-IR、1H-NMR对聚合物结构进行确认。结果表明当羧基与羟基摩尔比为1.6:1,对甲苯磺酸质量分数为0.15%,甲苯质量分数为25%,反应时间6h时,反应转化率为87.9%。In this work, a UV-curable fluorine-containing resin were synthesized by the esterification of fluoro-olefine vinyl ether （FEVE） and acrylic acid, and the structure of the yield resin were proved by FF-IR and ^1H NMR. The influences of the carboxyl/ hydroxyl ratio, the amount of catalyst and water carrying agent, and reaction time on conversion were investigated. The results showed that conversion rate was 87. 9% under the optimal conditions.
