| Abstract: | The reactive terminated polyethylene glycols was synthesized by maleic anhydride and polyethylene glycol and used as a modifier for the epoxy acrylate resin. The products was characterized by FTIR and 1H-NMR spectroscopy. The influence of reaction temperature and time on the reaction and properties of reactive polyethylene glycol discussed. The cured of reactive polyethylene glycol and epoxy acrylate resin was characterized by FTIR. The results indicate that the reactive polyethylene glycols participate in the curing reaction of the epoxy acrylate resin and introduce soft segments into the network, which has significantly increased the impact strength of the epoxy acrylate resin. |
