| Abstract: | Derivatives of 2-methylimidazole amidate and their carboxylic acid salts were synthesized by amidate reaction of carboxylic acid and 2-methylimidazole. Their structures and properties were studied. It was found that the 2-methylimidazole amidate derivatives and their carboxylic acid salts had lower curing activities and better latent properties than those of 2-methylimidazole. They also had better compatibility with epoxy resin than 2-methylimidazole, thus clearly improving mixed process operability of epoxy resin curing system. Mechanical properties of epoxy resin thermosets of 2-methylimidazole amidate derivatives and their carboxylic acid salts were better than those of 2-methylimiadzole. |
