Abstract
Abstract Poly(o-nitro)imides have been synthesized by one-stage polycondensation in DMAc at 130°C of 1,3-dichloro-4,6-dinitrobenzene with the di-potassium salt of pyromellitic or 3,3′,4,4′-benzophenonetetracarboxylic acid diimide. The structure was confirmed by elemental analysis, IR, and UV-Vis spectroscopy, and the influence of the o-nitrosubstituents on the solubility and the thermal stability of the prepared polymers was studied. These polymers could be used as pyrrone precursors. The model compound for these polymers has been also prepared by condensation of 1,3-dichloro-4,6-dinitrobenzene with potassium phthalimide.
