“…This irregularity is due to the fact that for the lower concentrations the hydrody- namic and the thermodynamic interactions between water and PEO are absent. [36] On the other hand, there is a large gap between the fluidity values for concentrations ≤10 mg/ml and the fluidity for the concentrations ≥20 mg/ml. To the contrary, the gap is reduced between the fluidity values for the various concentrations ≥20 mg/ml.…”

The self-assembly behaviour of poly(ethylene oxide)-b-poly(propylene oxide)-b-poly (ethylene oxide) copolymers, (EO) 13 (PO) 30 (EO) 13 (Pluronic L64), and (EO) 70 (PO) 30 (EO) 70 (Pluronic F68) in water and in p-xylene has been elucidated by using viscosity and dynamic light scattering measurements to investigate the effects of hydrophilic chains length on their conformational changes. The viscosity measurementswere performed for a range of temperature varying from 27 • C to 60 • C and concentration from 4 to 60 mg/ml. The variation of the viscosity and the conformational changes in aqueous solution depends on the kinds of interactions and the balance between excluded volume effects and hydrophobic interactions. Some dynamic light scattering measurements were also performed at room temperature for the same range of concentration to provide more information on the micellar structures in aqueous and organic solution.

“…The previous findings indicate that addition of ionic and nonionic solutes to aqueous PVP solutions disrupts hydrogen bonds or molecular association of polymers. Also, the intrinsic viscosity of PVP was decreased by increasing temperature [7][8][9][10][11]. Although PVP is easily soluble in water, the results of viscometric investigations indicate that water is not a thermodynamically good solvent for PVP [12][13][14].…”
