Synthesis of a Novel UV-Curable Diluent Benzyl Glycidyl Ether Acrylate and Its Application

A novel UV-curable diluent benzyl glycidyl ether acrylate (BGEA) was synthesized by utilizing benzyl glycidyl ether (BGE) and acrylic acid (AA) as starting materials,N,N-dim ethylbenzylamine as catalyst and p-hydroxyanisole as inhibitor.The optimum synthetic conditions were that the concentration of N,Ndimethylbenzylamine was 0.90％ of reactants by weight,the concentration of p-hydroxyanisole was 0.20％ of reactants by weight the reaction temperature was 90-100℃,and the molar ratio of BGE to AA was 1.00:1.10.The experiment shows that BGEA is a kind of good diluent.The mechanical properties of the UV-cured films with BGEA as diluent to prepare UV-curing coating were superior to that of the UV-cured films with butyl acrylate as diluent to prepare UV-curing coating.
