Abstract: Two bio-based seven-membered cyclic carbonate monomers M1 and M2 were synthesized in three steps from myrcene, which could produce polycarbonates via ring-opening polymerization using metal or organic catalysts. The functionalizable olefin moieties in resulting polycarbonates have driven post-polymerization modifications via radical cross-linking and hydrogenation, enabling the resulting polymers with tunable thermal properties. More importantly, the chemical recycling of P(M)s was achieved through "monomer → polymer ⇄ dimer", which presented a platform for the synthesis of chemically recyclable biobased polycarbonates.
