A bio-based polymer material FMDA-ESO containing ester and D-A bonds was synthesized from epoxidized soybean oil(ESO), N, N'-(difuranyl)-1, 8-p-menthane diamine(FMDA), maleimidic caproic acid and adipic acid. The materials were characterized and tested by Fourier transform infrared spectroscopy(FT-IR), differential scanning calorimetry(DSC), thermogravimetric analysis(TG) and universal test tester. The results showed that the cross-linked structure was formed in FMDA-ESO with the presence of ester and D-A bonds, and the rigid structure of FMDA could improve the mechanical properties of the obtained materials. With the amount increasement of FMDA in the FMDA-ESO cured formulation, the thermal stability of the material increased. Rapid degradation of FMDA-ESO could be achieved in the presence of ethanolamine, which could be degraded to oligomers with a number-average molecular weight of 2 691 at 135 ℃ for 30 min.
