Breaking the symmetry of dibenzoxazines: a paradigm to tailor the design of bio-based thermosets

Abstract

Asymmetric di-benzoxazine monomers from naturally occurring phenolic compounds – cardanol and vanillin – were synthesized to obtain a processable and self-supported bio-thermoset with valuable properties. Such strategy constitutes an efficient and versatile route for the elaboration of biobased thermoset from a wide range of phenolic compounds derived from renewable resources.
