high mechanical strength and thermoplastic reprocessability without compromising the material structural integrity. Since their discovery , epoxy vitrimer systems are the most widely studied class due to the current dominance of epoxy systems in the composites industry relative to other resins such as phenolics, benzoxazines, bismaleimides, and polyimides. There is currently a research focus on the design of polybenzoxazine vitrimers as alternatives to epoxies, motivated by the advantages of polybenzoxazines compared to both epoxies and phenolics in terms of thermomechanical and hygrothermal performances, fire retardancy, low cure shrinkage, molecular design flexibility, dimensional stability, and compatibility with sustainable precursors.
