A series of dynamic covalent network films, which contain catalyst-free, room temperature dynamic thia-Michael bonds, were used to understand structure/property/processing relationships in materials that exhibit dynamic reaction-induced phase separation (DRIPS). The combination of dynamic bonds in a phase separated system yielded materials with shape memory behavior and facile reprocessability. Interestingly, it was possible to use a tempering process to effectively ‘program’ the mechanical properties of the films, resulting in materials that could be readily converted from brittle to rubbery without changing the chemical composition of the network.
