Abstract

The objective of this study was to characterize the curing behavior of a crosslinking epoxy resin system consisting of dialycidyl ether of bisphenol A (DGEBA) and z-ethyl-4-methylimidazole (EMI-24) to determine if the reaction mechanism proposed for phenyl glycidyl ether (PGE)-based systems could be extended to crosslinking epoxies and to examine the effects of the etherification reactions on the final properties of the thermoset. Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) were used to establish the reaction mechanism and to evaluate the resin properties. The reaction mechanism for DGEBA cured with EMI-24 was then compared to the mechanism proposed for PGE.
