概要	Mixtures of tung oil (TO) and 4,4’-bismaleimidodiphenylmethane (BMI) in the molar ratios of 1:3 and 2:3 were cured at 100 ℃ or 160 ℃ to produce the cured products (TB13, TB23 or htTB13, htTB23). Fourier-transform infrared spectroscopy of the cured products confrmed that the trans, trans-diene moieties of TO are almost completely consumed for all the cured products; furthermore, the maleimide groups were almost completely consumed for all the cured products, except for TB13. Diferential scanning calorimetry results of the cured products revealed that TB13 and TB23 exhibited strong endothermic peaks due to the retro-Diels–Alder (rDA) reaction. The rDA enthalpy change (ΔHrDA) of TB13 was higher than that of TB23, and the ΔHrDAs of htTB13 and htTB23 were considerably smaller than that of TB13 and TB23. Although TB13 and TB23 exhibited self-healing properties upon hot-pressing at 100 and 120 ℃, respectively, htTB13 and htTB23 exhibited no self-healing ability.
