A hyperbranched bisphenol A derivatives epoxy resin(HPHEP) has been prepared by using the self-prepared bisphenol A derivative(Ph-BPA) and trimethylolpropane as raw materials via A2+B3 polycondensation. Further, a hyperbranched bisphenol A derivatives epoxy acrylate(HPHEA) is successfully synthesized by modifying the end group of HPHEP. The structure of polymers were characterized by FT-IR, UV-Vis spectra and 1H NMR spectra. The result of thermal gravimetric curve of the HPHEA shows that the main temperature range of weight loss is between 320~450 ℃, indicating a good heat resistance. In addition, the mechanical properties of the HPHEA UV-cured film exhibits excellent mechanical properties.
