A thermoplastic high strain multishape memory polymer can be fabricated using a hemiphasmid side‐chain polynorbornene ( P1 ) with hexagonal columnar liquid crystalline ( Φ H ) phase. Without any chemical crosslinks, P1 can memorize multiple temporary shapes with high strain and exhibit excellent shape fixity and shape recovery. As the building blocks of Φ H , the multichain columns in P1 act as robust physical crosslinks.
