The compressibility of polymer solutions was measured by the ultrasonic method (in Mc range). The partial specific compressibility of polymer in the solution was determined, and they yielded information about the polymer in the solution.
The information on the polymer were divided into the following two parts: (1) the response of a spherical polymer chain in the solution as a pearl necklace model, (2) the response of a mixing unit of the polymer chain as a pearl in necklace.
The response of a spherical polymer chain was proportional to the intrinsic viscosity of each solution, and was related to the chain dimentions as the viscometric expantion parameter was. On the other hand, the compressibility of a mixing unit of the polymer was the specific value of each component.
