| Abstract：UV-curable epoxy acrylates were prepared by reacting E-44 and E-12 epoxy resin with acrylic acid in the presence of onium salt. The effects of synthesis condition, such as the kinds and concentration of catalyst on synthesis reaction and product properties were discussed. The best concentration of catalyst and reaction time have also been gotten. |
| Key words：catalyst; onium salt; UV-curing; acrylated epoxy; reisn |
