A difunctional 1,3‐benzoxazine compound, 2,2′‐(3‐phenyl‐4‐dihydro‐1,3,2‐benzoxazine)propane ( B‐a ), derived from bisphenol‐A, 15 N‐enriched aniline, and formaldehyde was synthesized and characterized using 15 N‐NMR and 13 C‐NMR spectroscopies. The observed resonances in the solid‐state 15 N‐ and 13 C‐NMR spectra showed good agreement with the calculated chemical shifts which are based on the chemical structure. The B‐a samples were cured at 150 and 200°C. The polymerization inspired peak intensity changes and line‐width broadenings in the NMR spectra. © 1998 John Wiley & Sons, Inc. J. Appl. Polym.
