Shape-Memory Effects in Polymer Networks Containing Reversibly Associating Side-Groups

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 dy...

Description
Summary:	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 of H‐bond dissociation.
