Direct synthesis of poly(benzoxazine imide) from an ortho -benzoxazine: its thermal conversion to highly cross-linked polybenzoxazole and blending with poly(4-vinylphenol)

A facile one-pot synthesis of a poly(benzoxazine imide), NDOPoda Bz, was prepared without the need for either the preparation of an amino-functionalized benzoxazine or subsequent thermal treatment.
