Lignin-based Non-Isocyanate Polyurethanes by transurethanisation: catalyst selection towards Covalent Adaptable Networks

Key Points

• The aim is to synthesize lignin-based non-isocyanate polyurethanes (NIPU) for creating recyclable materials.
• Synthesis of NIPU through transurethanisation (TU) technique
• Selection of optimal catalysts for TU
• Conducting a kinetic study of the TU process
• Successful synthesis of lignin-based NIPU
• Identification of effective catalysts for TU
• Demonstration of recyclable properties in covalent adaptable networks (CANs)
