Abstract
An anomalous flow response of electric properties was observed in 0.01 wt% aqueous solutions of polyacrylic acid sodium salt (NaPAA) by electric measurements under shear flow using a newly developed apparatus. This response is considered to be caused by the migration of PAA<sup>-</sup> ions being intercepted by the turbulent flow generated by the high shear rate, resulting in the inability to form macroscopic polarizations.
