Bisphenol A based epoxy thermosets involve both environmental and health risks. By reacting a vegetal oil-based epoxide with an aromatic diacid containing S-S bonds a thermoset is produced. Herein, reprocessable thermosets were synthesized, the recyclability being designed through a dual mechanism: that of disulfide metathesis and of transesterifications. To assess the feasibility of the reprocessing, a series of ten initiators were tested to probe their effect not only on the crosslinking reaction but also on the recyclability. This study introduces for the first time the key role of the initiator on the material performances and on their reprocessing. A very good reprocessability was obtained for thermosets prepared using as initiator the imidazole. Moreover, the thermosets exhibit complete chem. recyclability in 1N NaOH at 80¡ãC, after 3 days, without needing addnl. chems. The reprocessed materials have similar performances with the virgin ones, even after 10 cycles of reprocessing.
