The absorption and velocity of ultrasound were studied for solutions of 10 000 molecular‐weight poly (ethylene glycol) and distilled water. The frequency used was 21 MHz and the concentration (by weight) ranged from 1% to 9% of poly (ethylene glycol) in water. The shear viscosity was also measured.Temperatures of 25, 30, 35, 40, 45 °C were used for the measurements. Observations showed that the ultrasonic absorption decreases with increasing temperature at a given concentration and also increases with concentration at a given temperature. The velocity increases with increasing temperature and concentration. Finally, the shear viscosity measurements show it decreasing with temperature but also increasing with concentration.
