A novel UV-curable prepolymer polypropyleneglycol diglycidyl ether diacrylate(PPGGEA) was synthesized by utilizing polypropyleneglycol diglycidyl ether(PPGGE)and acrylic acid(AA)as starting materials,N,N-dimethylbenzylamine as catalyst and p-hydroxyanisole as inhibitor.The optimum synthetic conditions were in the following:the concentration of N,N-dimethylbenzylamine was 0.80 wt% of reactants,the concentration of p-hydroxyanisole was 0.3 wt%of reactants.the reaction temperature was 90-110℃,and the molar ratio of PPGGE to AA was 1:2.2.Meanwhile,1-hydroxycyclOhexyl phenyl ketone of a UV-cured initiator was added to the synthesized PPGGEA to prepare a kind of UV-cured coating.The mechanical properties of the UV-cured films were determined,giving 29.99 MPa of tensile strength,834.27 MPa of the Young’S modulus and 5.66%of elongation at tear.
