Benzoxazines derived from bisphenol-A, formaldehyde, and primary amines were characterized using 13 C solid-state NMR spectroscopy. The two 1,3benzoxazines studied in this work are 2,2Ј-(3-methyl-4-dihydro-1,3,2-benzoxazine)propane, (B-m) and 2,2Ј-(3-phenyl-4-dihydro-1,3,2-benzoxazine)propane (B-a).

A difunctional 1,3-benzoxazine compound, 2,2Ј-(3-phenyl-4-dihydro-1,3,2benzoxazine)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-N
