Minimal N-hydroxyphthalimide-urethane bonds enable superior thermomechanical stability for covalent adaptable networks

The reprocessability of covalent adaptable networks often comes at the expense of mechanical performance and thermomechanical stability. Herein, the authors introduce a dynamic N-hydroxyphthalimide-urethane bond to achieve thermomechanical stability and reprocessability in covalent adaptable networks.
