Biomass eugenol derived polyols with two or three functionalities were synthesized and used for the preparation of self-healing polyurethanes PU-2SH and PU-3SH, respectively. The structure of PU-2SH and PU-3SH were characterized by Fourier transition infrared spectroscopy (FTIR). Variable temperature FTIR and swelling test were carried out to analysis the self-healing behavior and determine the self-healing temperature of PU-2SH and PU-3SH. The thermal stability, dynamic mechanical properties, swelling performance and self-healing performance of the prepared PU-2SH and PU-3SH were studied in detail. Compared with PU-2SH, PU-3SH showed higher stability, Tg and storage modulus, and weaker self-healing abilities.
