The dependence of viscosity, relative viscosity and the thermodynamic functions of activation for fluid flow of Investigated solutions on the concentration and temperature has been discussed. The conclusions about the effect of NaI and acetamide on the structure of investigated systems have been drawn.; Zmierzono lepkość roztworów NaI w mieszanych rozpuszczalnikach wodnoacetamidowych w zakresie temperatury 25-85°C. Przedyskutowano zależność lepkości, lepkości względnej oraz termodynamicznych aktywacji lepkiego przepływu badanych roztworów w zależności od stężenia roztworu i temperatury. Wysnuto wnioski dotyczące wpływu NaI i acetamidu na strukturę badanych układów.
