A series of block copolymers (BCPs) were synthesized and characterized. The linear BCPs showed low shape recovery ratio due to the lack of sufficient phase separation and chain entanglement. On the contrary, a crosslinked BCP that was synthesized by incorporation of the bifunctional polymer C‐BCP demonstrated excellent shape memory effect both on the macroscopic and microscopic scales.
