Influence of the ultrasound (US) on the formation of hydrogen bonds in acrylic acid (AA) and N-isopropylacrylamide (NIPAM) polymer P(NIPAM-co-AA) was investigated. It was expected that the sonic wave led to change the breaking ability of the hydrogen bonds between AA and NIPAM under US exposure. The polymer solutions contained 4g P(NIPAM-co-AA) in 96ml water was used. In the polymer solution, viscosity was measured when B type viscosity meter was used with 6 and 60 rpm rotation after exposure of different frequency (28, 45, 100 kHz) and the power of US (200W). It was found that hydrogen bonds were broken by irradiating the US. As a result, the viscosity of the solution decreased and increased with and without the exposure of US
