To improve the performance of traditional polybenzoxazines, copolymerized 3-phenyl-3,4-dihydro-2H-1,3-benzoxazine (Pa) and bisphenol-A benzoxazine (Ba) with three kinds of cyclotriphosphazene (CP)-based benzoxazine monomers, respectively. The ring-op

In the title compound, C16H13N5O2S, the five non-H atoms of the urea linkage adopt a planar configuration owing to the presence of an intramolecular N—H...O hydrogen bond. The maximum deviation from planarity is 0.022 (2) Å. The thiadiazole and py
