摘　　要：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.
