Abstract
Degradable shape-memory polymer networks intended for biomedical applications are highlighted. These polymer networks were synthesized from oligo(ε-caprolactone)dimethacrylate (PCL), or oligo[(L-lactide)-ran-glycolide]dimethacrylate (PLG), or from starlike hydroxytelechelic oligo[(rac-lactide)-co-glycolide] and a low molecular weight linker. While the thermal transition related to the switching phase is a melting point in case of the PCL-based materials, the switching transition of oligo[(L-lactide)-ran-glycolide]dimethacrylate networks and copolyesterurethane networks is a glass transition. In this chapter, the influence of the nature of thermal transition on the shape-memory behavior of polymer networks is described. Furthermore, different polymer network architectures are introduced, which enable the tailoring of polymer network properties as well as the shape-memory capability.
