摘要

<正> Ultrasonic absorption and velocity measurements were made on aqueous solutions of poly （ethylene glycol）（PEG）of different molecular weights and concentrations

using a pulse sender-receiver ultrasonic generator

Measurements were obtained at a frequency of 2MHz.

and a temperature of 293 K. The results show a linear increase of the Values of velocity

density and viscosity with increase of molecu lar weight and concentration of PEG. On the contrary

the attenuation values decreased with increase of molecular weight and concentration of PEG. A mathematical equation correlating relaxation amplitude and molecular weight of the polymer is suggested. This was applied to calculate the molecular weights of unknown samples of PEG from their measured relaxation amplitude. The results obtained were in good agreement with those obtained from osmometry.
