A new type of lightly crosslinked shape-memory polymer that contains reversibly associating side-groups is reported. H-bonding interactions stabilize mechanically strained states at low temperatures. The materials' shape recovery rate exhibits Arrhenius-like temperature dependence due to the dynamics H-bond dissociation.
