b) Shear range 2 at medium shear rates: the “flow range”

Оглавление

At increased shear rates, the number of disentanglements is more and more exceeding the number of the re-entanglements. As a consequence, the polymer shows shear-thinning behavior, and therefore, the curve of the viscosity function η( γ ̇ ) is decreasing now continuously (see Figure 3.10, range 2).
