Abstract

In present study, precise density, ultrasonic velocity and viscosity measurements have been carried out on PVP in water, methanol, ethanol, acetonitrile, 1-propanol, 2-propanol and 1-butanol at T = (288.15, 293.15, 298.15, 303.15, 308.15 and 313.15) K at atmospheric pressure. From these experimental data, the infinite dilution apparent specific volume and isentropic compressibility values of PVP in the investigated solvents have been obtained and their variations with temperature and type of solvents have also been obtained.
