    Abstract

    The viscometric functions for shear flow as predicted by the inextensible reptating rope model have been analysed numerically and analytically. The results obtained are compared with the predictions of the Curtiss—Bird theory. It is shown that if the correlation length of the rope is small as compared to its contour length significant deviations from the Curtiss—Bird theory are obtained. Results are presented for: (a) the onset of shear flow, (b) steady state shear flow and (c) small amplitude oscillatory shear flow.
