Effect of inorganic salts on viscosities of dimethyl sulphoxide(DMSO)solutions of acrylonitrile(AN)/N-vinylpyrrolidone(N-VP) copolymer was discussed. Viscosity was determined by revolving viscosimeter. It was shown that solution viscosity decreased quickly with addition of KCl and NaCl and the effect of NaCl was more prominent than KCl. As the concentration of KCl and NaCl beyond 0.025mol*L-1, the viscosity tended to increase. The viscosity increased considerably with addition of FeCl3 and CuCl2. The change of solution viscosity became less obvious with addition of ZnCl2.With increasing temperature, the viscosity of copolymer solution containing NaCl decreased most quickly and the copolymer solution containing FeCl3 decreased most slowly.
