Polyurethane based on plant phenols

Herein, the chemical structure and feedstock of typical plant phenolic are presented, and then, the synthesis of bio-based polyols from several key plant phenolics by different methods is summarized. Finally, the development of polyurethanes from phenolics through a nonisocyanate pathway is reviewed. The objective of this work is to summarize the recent progress on polyurethane based on plant phenolic-based polyols and nonisocyanate routes, which can help to promote the sustainable development of polyurethane.
