Herein, first, the terpolymerization of CO<jats:sub>2<\/jats:sub>, propylene oxide (PO), and epichlorohydrin (ECH) to synthesize PPC\u2010ECH terpolymers via one\u2010pot and metal\u2010free method using multinuclear organoboron catalysts is reported. The PPC\u2010ECH terpolymers with well\u2010rounded properties can be easily synthesized by adjusting reaction conditions, monomer ratios, catalyst types, and loading. The molecular weight of the PPC\u2010ECH terpolymer can reach up to 59.4\u2009kg\u2009mol<jats:sup>\u22121<\/jats:sup>, which is the highest known. Notably, the synthesized PPC\u2010ECH exhibits outstanding barrier performance with oxygen permeability as low as 1.31\u2009cm<jats:sup>3<\/jats:sup>\u2009mm\u2009(m<jats:sup>2<\/jats:sup>\u2009day)<jats:sup>\u22121<\/jats:sup> and water vapor permeability as low as 0.016\u2009g\u2009mm\u2009(m<jats:sup>2<\/jats:sup>\u2009day)<jats:sup>\u22121<\/jats:sup>, significantly lower than those of pure PPC or other common packaging materials. Importantly, the introduction of a small amount of ECH not only preserves the biodegradability of polycarbonate but also markedly enhances its mechanical properties, glass transition temperature, thermal stability, and flame retardancy, offering promising prospects for application in packaging materials.<\/jats:p>","DOI":"10.1002\/cplu.202500175","type":"journal-article","created":{"date-parts":[[2025,4,17]],"date-time":"2025-04-17T23:04:11Z","timestamp":1744931051000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["High\u2010Molecular\u2010Weight Biodegradable CO<sub>2<\/sub>\/Propylene Oxide\/Epichlorohydrin Terpolymers with Outstanding Gas Barrier Performance Synthesized Using an Organoboron Catalyst"],"prefix":"10.1002","volume":"90","author":[{"given":"Yufei","family":"Liang","sequence":"first","affiliation":[{"name":"The Key Laboratory of Low\u2010carbon Chemistry &amp; Energy Conservation of Guangdong Province State Key Laboratory of Optoelectronic Materials and Technologies School of Materials Science and Engineering Sun Yat\u2010sen University  Guangzhou 510275 P.
