To improve the electrical conductivity of acrylonitrile film, acrylonitrile copolymer was synthesized conductive polymer, which was acrylonitrile-sodium-p-styrene sulfonate complex induced by CuxS. The conclusion obtained from this study are as follows: 1. CuxS-AN-SS film was much influenced by pH, concentrations of CuSO4, (NH3OH)2 SO4, Na2S2O3 and reaction time. 2. The volume and surface resistivities of CuxS-AN-SS was increased by order of 106(cm) in volume resistivities, 107(cm) in surface resistivities than that of AN-SS. 3. The Tm value of CuxS-induces copolymer was lower than that of AN-SS copolymer. 4. The tensile properties of CuxS-AN-SS were generally decreased, and particulary the tensile strength of CuxS-AN-SS was decreased about 45% as compare with that of AN-SS.
