The copolymerization of naidc and methyltetrahydrophthalic anhydrides and diglycidyl ether of bisphenol A (DGEBA) with various stoichiometric ratios [ r = 2[anhydride]/DGEBA] and with different concentrations of several imidazoles has been studied. These results are compared with those obtained with a tertiary amine such as benzyldimethylamine, a well‐known efficient catalyst of epoxy‐anhydride copolymerization. Thermal and hydrothermal behaviors of these networks also have been examined.
