Biodegradable body temperature‐responsive shape memory polyurethanes, with self‐healing function, were synthesized here from PCDL, MDI and different chain extenders, in which the chain extenders are designed to adjust their transition temperatures and shape memory properties. Once deformed at proper temperature, they show more than 96% shape fixation until heated near body temperature, where they recover their original shape (100%) within 20 s. Moreover, these polyurethanes could be self‐healing at proper temperature, which makes them available in many medical fields. POLYM. ENG. SCI., 59:E310–E316, 2019. © 2019 Society of Plastics Engineers
