Copper-Catalyzed Access to Non-Isocyanate Polyurethanes from N-formamides and Biobased Phenols
Résumé
A copper catalyst promotes dehydrogenative couplings of phenols with minimal or no excess of Nformamides • This method is applied to prepare two biosourced urethane monomers, free of isocyanates • Dehydrogenative coupling and thiol-ene click polymerization create isocyanate-free polyurethane thermosets
• Isocyanates are replaced by CO₂-derived N-formamides to prepare Non-Isocyanate PolyUrethanes (NIPUs)
• The physicochemical and mechanical properties of NIPU thermosets are investigated.
