A novel compound, 1,5-bis(2-aminoethylamino)-2,4-dinitrobenzene(BDB), was synthesized for incorporation of nonlinear optical units to the polymer main chain. Polyamide-amines were obtained by interfacial polycondensation reaction of BDB with several aliphatic diacid chlorides. These polymers were characterized by viscosity measurement, thermal analysis, infrared, and ultraviolet spectroscopes.
