摘　　要：通过一元羧酸与2-甲基咪唑进行酰胺化反应制备咪唑酰胺化衍生物及其盐,并对咪唑酰胺化衍生物及其盐的结构与性能进行表征.结果表明:咪唑酰胺化衍生物及其盐可降低咪唑的固化反应活性,提高潜伏性;可显著改善与环氧树脂之间的相容性,从而提高工艺操作性;可明显提高环氧树脂固化物的力学性能.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.
