Bio-based cyclic carbonates
WebOct 22, 2024 · Bio-based cyclic carbonates are of significant research interest as monomers for non-isocyanate polyurethanes (NIPUs). In this work, novel and bio-sourced NIPUs were prepared and characterized. WebFunctionalized cyclic carbonates are attractive monomers for the synthesis of innovative polycarbonates or polyurethanes for various applications. Even though their synthesis has been intensively investigated, doing so in a sustainable and efficient manner remains a challenge. Herein, we propose an organocatalytic procedure based on the …
