| Abstract: |
| Polyurethane （PU） is one of the most widely used polymer materials， in which area the synthesizing technology of non-isocyanate polyurethane （NIPU） from biomass resources is receiving increasing attention. Lignin is a natural and renewable aromatic polymer with abundant reserves in nature. Functionalized lignin can be a substitute for the unsustainable petroleum-based raw material in developing high value-added NIPU products. This paper reviewed methods and strategies for synthesizing NIPU using lignin as a raw material， summarized the research progress regarding synthesizing lignin-based NIPU using lignin and its functionalized derivatives， as well as prospected the potential applications of lignin-based NIPU in foam materials， wood adhesives， elastomers， coatings and other related fields. |
