Thiol–Ene Networks with Tunable Dynamicity for Covalent Adaptation

To be fully recyclable, covalent adaptable networks must ultimately able to overcome all topological restrictions and flow. By using a statistically based method, it was shown that the extent of stress relaxation in disulfide-containing thiol–ene polymers is closely correlated fraction permanent cross-links. Given sufficient disulfide content, cured materials can recycled at moderate temperatures with no apparent loss tensile properties. Since also feature ester bonds, even when content low, one increase reprocessing temperature trigger transesterification reactions which ensure full recyclability.
