The curing of epoxy resin with SMA as the curing agent and MeIm as the accelerator was studied by FT-IR and DSC, and the thermal stability of the resin was studied by DTA-TG analysis. The surface morphology of the cured product was studied by SEM. The curing mechanism was discussed. The result indicates that SMA can be used alone as the curing agent for epoxy resin, and the curing temperature could be decreased by 10℃ when MeIm was added as an accelerator, and the cured product exhibited thermal stability at below 400℃. There were two phases in the cured product, the continuous phase being epoxy and the dispersed phase being SMA.
