An epoxide-acrylate hybrid oligomer was synthesized by reaction of bisphenol A epoxy resin and acrylic acid and its photopolymerization kinetics were investigated using, real-time infrared spectroscopy. The influences of photoinitiator concentration on the polymerization kinetics and the unique photopolymerization kinetic character were compared with the Wend system of epoxy resin and epoxy acrylate and discussed. The hybrid oligomer showed some inter-group interaction in the photopolymerization process, which could decrease the oxygen inhibition to radical process. The mechanical properties were explored by DMA. Hybrid oligomer cured film showed a more uniform polymer net and higher T-g than the blend of epoxy acrylate and epoxy resin.
