Notes:
Polyureidoborazines were synthesized by the reaction of tri-isocyanato-trimethylborazine with linear aliphatic diamines. The insoluble oligomers were characterized by infrared spectroscopy and the effect of the number of methylene units on thermal transitions determined by differential scanning calorimetry (DSC). The oligomers were pyrolyzed in argon and ammonia-nitrogen atmospheres and the residues analyzed for boron, nitrogen atmospheres and the residues analyzed for boron, nitrogen and carbon.
