Conditions

Temperature
80 °C

Procedure

34.8 g of bisphenol A diglycidyl ether was heated to 70° C. under continuous stirring and then 14.4 g of acrylic acid was added slowly under nitrogen atmosphere. After maintaining the reaction at 70° C. for 2 hours, 19.6 g of maleic anhydirde was added and then the temperature was raised to 80° C. under mechanical stirring for 2-3 hours to complete the reaction.
