One kind of vinyl ester has been synthesized by treating epoxy resin with acrylic acid in toluene and characterized by Fourier transform infrared spectroscopy (FTIR). FTIR results showed that the epoxy resin is indeed reacted with acrylic acid through epoxy group and carboxyl of acrylic acid. The influences of reaction factors have been studied in detail. Experimental and properties testing results showed that this kind of vinyl ester, which obtained under the conditions of the temperature is 100 °C, amount of catalyst is 1.0 wt% and the feed ratio is 1.02:1(the molar ratio of acid to epoxy), is suitable as thickener for SMC(Sheet Moulding Compound).
