Polybenzoxazines: new players in the bio-based polymer arena

Polybenzoxazines are phenol-like materials that have attracted significant attention from both academia and industry because of their unique advantages. The growth of this technology has always been linked to petro-based feedstocks. However, due to the incessant global energy crisis it is now finding a breakthrough through the preparation of their monomers from renewable resources. This mini-review focuses on the recent efforts to replace petro-based feedstocks with polybenzoxazine precursors.
