Abstract

The thermal and volumetric change properties of diglycidyl ether of bisphenol A (DGEBA) epoxy resin were studied using two thermal cationic catalysts: benzylquinoxalinium hexafluoroantimonate (BQH) and triphenyl benzyl phosphonium hexafluoroantimonate (TBPH). The cure reactivity and thermal stability of the DGEBA/BQH system were higher than those of the DGEBA/TBPH system; this was because of the slow thermal diffusion rate of the DGEBA/TBPH system induced by the bulky phenyl groups in TBPH. The volumetric change values of DGEBA/BQH and DGEBA/TBPH were −0.17% and 7.95%, respectively.
