| Abstract: | Ultrasonic velocity (U), viscosity (η), adiabatic compressibility (βa) and viscous relaxation time (τ) have been measured in binary mixtures of polyvinyl chloride (PVC) and polyvinyl acetate (PVAc) in tetrahydrofuran (THF) at different temperatures 298, 303, 308, 313 and 318K at frequency 2 MHz. The observed maxima in ultrasonic velocity, viscosity, relaxation time and minima in adiabatic compressibility are attributed to molecular interactions between PVC and PVAc due to proton donor-acceptor interactions. |
