Two vanillin-based photocurable, thermally reprocessable, and chemically recyclable imine
thermosets were successfully designed. The vanillin vitrimer resins were synthesized
through a protocol with a two-step reaction: methacrylation and imination with diamine or
triamine. The obtained vinyl ester resins with imine bonds and vinyl groups could be
photocured into thermosets in 10 min at room temperature. The cured thermosets had good
solvent resistance against common solvents, good thermal stability up to about 250° C as …
