magnetic resonance (NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and elemental analysis, and the polymerization of BA-PABN was investigated by FTIR, solid-state 13C NMR, and differential scanning calorimetry. BA-PABN undergoes the oxazine ring-opening polymerization and the cyclotrimerization of cyano groups with the formation of the corresponding polybenzoxazine (PBA-PABN). Dynamic
