Various types of poly(nitroarylates) ( 8 – 17 ) were prepared using interfacial polycondensation (IPC) and solution polycondensation (SPC) of 5‐nitroiso‐phthaloyl chloride ( la ) and 2‐nitroterephthaloyl chloride ( 2a ) with different bisphenols: hydroquinone ( 3 ), resorcinol ( 4 ), 4.4′‐dihydroxydiphenyl ( 5 ), 2,2‐bis(4‐hydroxyphenyl) propane ( 6 ) and bis(4‐hydroxyphenyl) sulfone ( 7 ). A nitro group was introduced in the polymeric chain in order to improve the properties, solubility and thermal stability of these polymers. Some of the factors affecting the IPC were studied, such as the effect of concentration of the initial components and the role of the solvent. The structures of the poly(nitroarylates) ( 8 – 17 ) were confirmed by elemental analysis, infrared and proton magnetic resonance spectrometry. Thermomechanical analysis (TMA) and thermogravimetric analysis (TGA) of the synthesized polymers were also studied.
