Abstract

Abstract The novel benzoxazine monomers, DPA-Bz and MDP-Bz from renewable diphenolic acid (DPA), which mimics the structure of bisphenol A (BPA), were synthesized by traditional approaches. The structure and purity of the monomers was confirmed by FTIR, 1 H NMR, and 13 C NMR spectra. The thermally activated polymerization of the MDP-Bz and DPA-Bz afforded thermosetting polybenzoxazines with higher T g's, 270 C and 208 C ...
