Figure 2From: Primitive chain network simulations for elongational viscosity of bidisperse polystyrene meltsTransient uniaxial elongational viscosities for Blend1, Blend2 and Blend3 from top to bottom. The strain rates (from left to right) are 0.3, 0.1, 0.03, 0.01 and 0.003 s−1 for Blend1, 0.1, 0.03, 0.01, 0.003 and 0.001 s−1 for Blend2, and 0.3, 0.1, 0.03, 0.01, 0.003 and 0.001 s−1 for Blend3, respectively. Unfilled circle is the data measured by Nielsen et al. [5] (the data for Blend2 were taken from van Ruymbeke et al. [11]). Red and blue solid curves are simulation results with and without SORF. Black dotted curve is the linear viscoelastic envelope for the simulation.Back to article page
