New monomer difurfurylamine easily obtainable from furfural (inexpensive biorenewable feedstock) was used for the synthesis of the polyurethane preform. The latest was cross‐linked with different amount of BMI (bismaleimide) via Diels–Alder reaction, and polymers with a high and low degree of cross‐linking were obtained and characterized. The self‐healing efficiency was investigated with differential scanning calorimetry, scanning electronic microscopy, X‐ray tomography, and tensile strength measurement end up to 95% restoration of mechanical properties was demonstrated for one composition after thermal treatment. © 2019 Wiley Periodicals, Inc.
