Melt processable poly acrylonitrile(AN)-co-vinylimidazole(VIM) polymers of different compositions were successfully synthesized by free radical polymerization in N-N'-dimethylformamide (DMF) solvent system . The copolymers were characterized by attenuated total reflectance-Fourier transform Infrared (ATR-FTIR) spectroscopy, 1H NMR spectroscopy, gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). Suitable thermo-chemical properties of these copolymers showed their applicability as a melt processable carbon fiber precursor, nitric oxide releasing enhanced wound healing materials and supercapacitors. The effect on the molecular weights and thermo-chemical properties of the polymer with variable initiator concentrations was investigated for optimizing the reaction parameters for high molecular weights. The synthesis of the polymers was also carried out in different solvent systems to study their effect on thermo-chemical properties by comparing the results obtained from DMF system.
