Overshoot of shear stress, , and the first normal stress difference, N 1 , in shear flow were investigated for polystyrene solutions. The magnitudes of shear corresponding to these stresses, β₯ m and β₯ Nm , for entangled as well as nonentangled solutions were universal functions of β₯ Λeq , respective
