摘要:

The absorption coefficient of ultrasound and shear viscosity in binary solutions of polyacrylamide with water were studied as a function of concentration and temperature. In addition, the absorption coefficient was measured as a function of frequency. The value of α/f2increased by twofold, at 3% concentration and 20 °C, from the water value while the shear viscosity increased by four orders of magnitude. The temperature dependence of α/f2for the polymer solutions is similar to that of pure water.
