Steady state viscosity as a function of strain rate for Blend1, Blend2 and Blend3 from top to bottom. Red and blue curves are the simulation results with and without SORF. Unfilled circle is the data extracted from Nielsen et al. . Horizontal dotted line is the Trouton’s viscosity. The reciprocal of the longest relaxation time τ
1, the (viscoelastic) Rouse relaxation times of the long and short chains, τ
RL and τ
RS, are also indicated at the horizontal axis.
