Thermosetting resins take an important position in the polymer field, while they rely on
limited and rapidly depleting fossil resources. Vanillin is currently the only industrialized bio-based
monomer with benzene ring from renewable and abundant lignin. In this paper, the need for developing
vanillin-derived thermosets as well as a summary of research progress is presented. Vanillinderived
thermosets are divided into several categories including epoxy resins, benzoxazines, phenolic
resins, methacrylates and other thermosets. Synthetic routes and the properties of the vanillin-derived
thermosets are described. Finally, conclusions and outlooks are highlighted.
Keywords: Cross-linked polymers, lignin, biomass, renewable bioresources, epoxy resins, methacrylates, vanillin.
