| Abstract: | Polyethylene glycol acrylate （PEGA） was synthesized by condensation of PEG （400） and methacrylic acid. 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% ,respeetively （aeeording to the mass of PEG and acrylic acid） . The structure of the PEGA was eharacterized by FF IR and ^1HNMR. Theester yield reached 81% according to ^1HNMR. |
