Abstract A new curing agent (PBMI-DDE) for epoxy resin was synthesized from phthalide-containing bismaleimide (PBMI) and aromatic amine (DDE) according to the Michael addition reaction. The chemical structure of PBMI-DDE was characterized by 1H NMR spectroscopy and Fourier transform infrared spectroscopy (FTIR). The curing performance and kinetics of E-51/ PBMI-DDE was studied by DSC. Apparent activation energy evaluated according to Kissinger model or FWO model is 46.7 or 49.1 kJ/mol, respectively, and the calculated reaction order is 0.88 based on Crane method. The DMA and TGA results show that the cured resin possesses excellent thermostability with a glass transition temperature 153℃ for the completely cured resin.
