Study of molecular interactions of polyethylene glycol in water

摘要

Different acoustical parameters have been calculated like ultrasonic attenuation and ultrasonic absorption by using measured values of ultrasonic speed, density and viscosity. The speed of ultrasonic waves has been measured in aqueous solution of polyethylene glycol at 1 MHz frequency. Measurements were carried out at temperature 30℃, at different concentration range 0.3% to 1.0%. By using these values intermolecular interactions are discussed.
