Abstract
Further investigation was carried out into the mechanism underlying the changes in electric resistance in an aqueous solution of poly(sodium acrylate) induced by a vigorous flow, as we had previously observed. The change in resistance increased with concentration and showed a broad peak at a NaPAA concentration of approximately 2 × 10<sup>-3</sup> wt%, which was close to the entanglement concentration (1.2 × 10<sup>-3</sup> wt%). The change in resistance of the NaPAA solution increased with increasing frequency and tended to reach a plateau above approximately 3 × 10<sup>3</sup> Hz. The absolute value of the change in resistance due to the flow could be quantitatively explained by the decrease in the polymer concentration.
