In this article we are prepared heat resistant polymer containing N-(4-Nitro phenyl) maleimide (PNPMI) and
Acrylonitile copolymerization under the identical conditions in DMF and THF solvent. The characteristics of the copolymer were analyzed by Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, gelpermeation chromatography, and elemental analysis.
