| Abstract: | Kinetics on the reaction of epoxy resin with acrylic acid has been studied. Mechanism of this reaction is proposed. Acrylic acid dissociates initially into carboxylatc anion and proton. Then the carboxylate anion undergoes nucleophilic addition to epoxy resin group, producing an alcoholate anion. The reaction is finally accomplished by the absorption of a proton. The rate of addition of acrylic acid to epoxy resin is first order. In addition, the influence of dissociation constants of the unsaturated acids and polarity of the solvents on the reaction rates is in agreement with the above suggested mechanism. |
