title: Molecular weight distribution and the electrorheological response for anisotropic solutions of poly(gamma-benzyl-L-glutamate) induced by the convection of the electrohydrodynamic instability.
abstract: Transient responses of stress to a sinusoidal electric field were reported for anisotropic solutions of poly(gamma-benzyl-L-glutamate)s (PBLG's) with different distributions of the molecular weight. The transient stress, which was induced by the convection of the electrohydrodynamic instability, showed a steep and large increase when it was plotted against the instantaneous amplitude of the electric field. The maximum stress of a PBLG solution tended to increase with an increase in the maximum molecular weight of the PBLG in the molecular weight distribution.
