Influence of different imidazole catalysts on epoxy‐anhydride copolymerization and on their network properties

摘要

AbstractThe copolymerization of naidc and methyltetrahydrophthalic anhydrides and diglycidyl ether of bisphenol A (DGEBA) with various stoichiometric ratios r= 2anhydride/DGEBAand 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 exami
