Polybenzoxazine resins are a class of high-performance phenolic resins which are utilized in the structural and engineering applications because they possess good flame retardance and thermal properties of phenolic resins, including high mechanical properties, such as good sound and noise absorption.Polybenzoxazine resins are synthesized from phenol or substituted phenols, aldehyde, such as formaldehyde, acid aldehyde, or pyromucic aldehyde, and amine groups. They can be synthesized via either solvent or solventless technology.
