Summary: Due to a large difference in storage modulus below and above the glass transition temperature, a novel shape‐memory poly[(methyl methacrylate)‐ co ‐( N ‐vinyl‐2‐pyrrolidone)]/poly(ethylene glycol) semi‐interpenetrating polymer networks structure was synthesized, which is stabilized by hydrogen‐bonding interactions. The recovery ratio of these polymers could reach 99%. In such a system the maximum molecular weight of PEG required for the semi‐IPNs formation reaches 1 000.Transition from the temporary shape (chem) to the permanent shape (four rods) for a shape‐memory P(MMA‐ co ‐VP)/PEG1000 semi‐IPNs.
