Abstract

The ultrasonic velocity, density, and ViScosIties of polyvinylpYITolidone (PVP) and cellulose acetate butyrate (CAB) solutions in dimethyllonnamide (DMF) have been measured in the temperature range, 303K-323 K. Using these data, free energy of mixing, solvation number and different polymer-solvent interaction parameters for the solution systems have been calculated to know the presence of molecular interactions in the system. The trends in the variation of the solution property parameters indicate the existence of positive molecular interactions between tile polymer and the solvent in solutions. The results also show the presence of higher degree of interaction between I'VP and DMF in solution compared to CAB and DMF.
