UV-curable polydimethylsiloxane epoxy acrylate (PESA) was synthesized by reacting epoxy polydimethylsiloxane with acrylic acid (AA). It is shown that the optimum synthesis temperature for PESA is 100-110 ยฐC and triethylamine is best one among those catalysts tested. The structure of the oligomer was
