Among renewable bioresources, limonene, a cyclic monoterpene abundant in citrus peels, has been extensively researched for functionalization or polymerization reactions. In this study, we synthesized highly branched limonene-based polymers via thiol-ene polymerization and further demonstrated the formation of reusable and degradable thermosets from the branched polymers. Following the design principles, many thiol groups were mainly positioned outer surface of polymer domain, affording the network formation with an aid of Meldrum’s acid-based cross-linkers. Thus, the thermosets could be readily recycled upon heating but degraded via aminolysis. The bio-based thermosets could be further reinforced with carbon fibers as being used as a matrix or binder, exhibiting the programmed responses.
