Cooling of hot solutions of K2 containing 38 mol.% of G4S-DA2S and 16 mol.% of G4SD2S,6S and G4S-D2S: (a) temperature dependence of the shear storage (G′) and loss (G″) moduli recorded during the cooling of a 4 wt.% solution in distilled water under an oscillatory strain of 4%; (b) Temperature dependence of the apparent shear viscosity η_app measured during the cooling of a 4 wt.% solution in 0.1 M NaCl under a steady shear of 0.05 s⁻¹ (green triangles), 0.3 s⁻¹ (black squares), and 3 s⁻¹ (red circles) [77]; (c) temperature dependence of the apparent shear viscosity η_app measured during the cooling of a 1.5 wt.% solution in 0.05 M KCl under a steady shear of 0.05 s⁻¹ (green triangles), 0.3 s⁻¹ (black squares), and 3 s⁻¹ (red circles) [78].
