...Polymer/OMLS nanocomposites [441 – 443] always exhibit significant deviations from the Cox– Merz relation [444], while all neat polymers obey the empirical relation, which requires that for _ g 1⁄4 v; the viscoelastic data obeys the relationship hð _ gÞ 1⁄4 lhplðvÞ: Two possible reasons may be offered for the deviation from the Cox–Merz relation in case of nanocomposites....

TL;DR: In this article, the concentration and shear rate dependence of viscosity has been studied for a wide range of random coil polysaccharide solutions, and the following striking generalities are observed: 1. The transition from dilute to concentrated solution behavior occurs at a critical concentration c ∗ ≈ 4 [η], when "zero shear" specific viscosities (ηsp) ≈ 10.
