Molecular Interactions in Binary Mixture of Polymethylmethacrylate with Acetic Acid

Richa Saxena, S. C. Bhatt


Solution is prepared by mixing Polymethylmethacrylate in solid form with acetic acid, which at different
concentration were used to measure density, viscosity & ultrasonic velocity in the temperature range 300C-650C,
using ultrasonic interferometer at 1MHz. Using these measured values of density, viscosity & sound velocity,
different parameters like, adiabatic compressibility, acoustic impedance and relaxation time have been measured
for solution of polymethylmethacrylate with acetic acid under different conditions of temperature and
concentration. Variations of above parameters with respect to temperature and concentration have been
discussed in terms of molecular interactions.
