| Abstract: | Glycol-diglycidyl ether diacrylate monomers were synthesized from various diglycidyl ethers and acrylic acid, and the effects of the ratio of reactants, the type and amount of catalyst, reaction temperature on the main reaction as well as the side-reaction were studied. The experimental results indicates that the optimum reaction conditions are as follows: molar ratio of epoxy group to carboxyl group=1∶0.95, mass fraction of triethylamine catalyst=0.36%, reaction temperature 100110℃. By suppressing of side reaction, the glycol-diglycidyl ether diacrylate with lower acid value and lower viscosity was obtained. |
