## Abstract Effects of inorganic salts on viscosities of dimethyl sulphoxide (DMSO) solutions of acrylonitrile(AN)/__N__‐vinylpyrrolidone(__N__‐VP) copolymer are discussed. Viscosity was determined by the rotary viscosimeter. It was shown that the solution viscosity decreases quickly with addition
The unperturbed dimensions and thermodynamic parameters of poly(vinylpyrrolidone) (PVP) have been studied in aqueous salt solutions, e.g. phosphates, mono-and dihydrogen phosphates, carbonates, sulphates of sodium and potassium. Values of where is intrinsic viscosity at # the theta temperature and
Electronic spectral behavior of poly(N-vinyl-2-pyrrolidone) (PVP) was determined in aqueous solutions including a variety of inorganic salts (phosphates, monoand dihydrogen phosphates, sulfates, chlorides, nitrates, bisulfites, and persulfates) for several concentrations. The n 3 \* excitations are
