| 摘 要： | 以聚乙二醇-400（PEG400）与丙烯酸直接缩合反应，在不加有毒带水剂的条件下合成了丙烯酸聚乙二醇酯（PEGA）。通过正交实验确定酯化反应的最佳条件：丙烯酸／PEG400的摩尔比为2．0：1．0，反应温度是110℃，阻聚剂对苯二酚为0．4％（以醇酸总质量计），反应时间为6小时，催化剂对甲苯磺酸为0．8％（以醇酸总质量计），产率为76．7％。产品结构经IR和1HNMR表征，证明是所需的产物。

| Abstract: | Polyethylene glycol acrylate ( PEGA) was synthesized by condensation of PEG( 400) and acrylic acid without water- car??rying reagent. The optimal condition of esterification was studied by the orthogonal design that the molar rate of acrylic acid to PEG was 2. 0: 1. 0,the reaction temperature was 110?? , the reaction time is 6h, the amount of hydroquinone and p- methy benzene sulfonic acid was 0. 4% and 0.8%, respectively ( according to the mass of PEG and acrylic acid) . The structure of the PEGA was characterized by FTIR, and 1HNMR. . Theester yield reached 81% according to 1HNMR. |
