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)

Implication

This work develops lignin-based non-isocyanate polyurethanes, indicating their potential as biobased recyclable materials.

Abstract

This work reports the synthesis of lignin-based non-isocyanate polyurethanes (NIPU) via transurethanisation (TU), aiming to develop biobased and recyclable covalent adaptable networks (CANs). A kinetic study of a model TU...
