Abstract
For the epoxy/N-benzylpyrazinium hexafluoroantimonate (BPH) system, the effects of cure temperature and composition of BPH on the cure kinetics were investigated in terms of isothermal and dynamic DSC analyses. The cure temperature range was 120-180°C and the composition of BPH on epoxy was varied with 0.5-5 wt.%. From DSC results of epoxy/BPH system, the reaction rate was strongly dependent on the increasing of the cure temperature or composition of BPH. These results could be explained by means of increasing the reactivity between the -OH functional group of epoxy and BPH when the cure temperature increased, and increasing the reactable active sites when the composition of BPH increased. The activation energies obtained from Kissinger equation increased as the composition of BPH decreased, resulting in the different reactivity between hydroxyl group within epoxy resin and BPH.
