Abstract Plastics derived from fossil feedstocks pose major recycling challenges, particularly crosslinked thermosets used in electronics, construction and composites. Polydiketoenamines (PDKs) are recyclable alternatives; however, monomers such as dimedone are petrochemical-derived and offer limited tunability. We computationally screened 144 β-keto-δ-lactones (BKDLs), identifying solvation free energy as the primary determinant of depolymerization temperature across a 20–60 °C range.
