Polyamides and Polyureas Containing s -Triazine Rings

Several new aromatic diamines containing s-triazine rings were prepared by the reaction of the related dinitro-compounds prepared from biguanide derivatives and carboxylic acid chlorides. Polyamides and polyureas containing amino-s-triazine were synthesized by the polycondensation of these diamines with dicarboxylic acid chlorides and diisocyanates respectively. Their preparations and physical properties are described.
