| abstract | (57) [Abstract] [PROBLEMS] To easily perform fumaric acid modification of a vinyl ester or vinyl ester modification of an unsaturated polyester by carrying out fumaric acid transfer of maleic acid at a low temperature, which normally has to be carried out at a high temperature. To aim. SOLUTION: In the fumaric acid modification of a vinyl ester obtained by the reaction of an epoxy compound and an unsaturated monobasic acid, maleic anhydride is added to the hydroxyl group of the vinyl ester by ring-opening addition, and then maleic acid in the molecule is transferred at a low temperature. Method for producing vinyl ester by facilitating fumaric acid modification of vinyl ester, and terminal maleic acid of acid-terminated unsaturated polyester oligomer obtained by ring-opening addition reaction of maleic anhydride to glycol in vinyl ester modification of unsaturated polyester After low-temperature transfer, the unsaturated polyester is easily modified with vinyl ester by reacting an epoxy compound with an unsaturated monobasic acid. [Effect] Since the transfer rate of maleic acid to fumaric acid can be stabilized with high efficiency, a stable product can be obtained. Further, it is possible to lower the manufacturing temperature and shorten the manufacturing time. |
