| Abstract: | A series of 2-methylimidazole amidate derivatives(MIAD) were synthesized by amidation reaction of multi-acid(MA) and 2-methylimidazole(MI).And the 2-methylimidazole amidate derivative salts(MIADS) were prepared by salification of MIAD and 2-ethyl hexanoate(EHA).The structures and properties of MIADS and thereof epoxy resin thermosets were characterized by Fourier transform infrared spectrum(FT-IR),dynamic mechanical analysis(DMA),thermogravimetric analysis(TGA) and mechanical properties testing.It is found that MIADS have lower curing activities and better latent properties than those of MI.And they also have better compatibility with epoxy resin than MI,which improving mechanical properties and heat resistances of epoxy resin thermosets obviously.It is proved that MIADS are a kind of imidazole curing agents for epoxy resin under middle temperature with excellent comprehensive performance. |
