  • Abstract

    Experimental values of density, viscosity and ultrasonic velocity of binary mixtures of polymethylmethacrylate with acetic acid studies have been carried out over entire concentration range 0.3% to 1.0% at 55 ?C temperature are reported. The measurements were carried out at 1 MHz frequency. From these different acoustical parameters adiabatic compressibility, acoustic impedance and intermolecular free length have been calculated by using measured values of ultrasonic speed, density and viscosity. The solute and solvent interactions are discussed
