Chemically recyclable polyesters from CO₂, H₂, and 1,3-butadiene.

ABSTRACT: Chemically recyclable solid polymeric materials with commercializable properties only using CO₂ and inexpensive bulk chemicals as chemical feedstock can open a brand-new avenue to economically viable, large-scale fixation of CO₂ over a long period of time. Despite previous great advancements, development of such a kind of CO₂-based polymers remains a long-term unsolved research challenge of great significance. Herein, we reported the first methodology to polymerize six-membered lactone with two substituents vicinal to the ester group (HL), a compound previously found to be non-polymerizable. The present methodology enables the first synthesis of chemically recyclable solid polyesters (polyHL) with a high CO₂ content (28 wt %) and la
