Spherical Polyelectrolyte Microgels in Salt-Free Solution. 2. Combined Analysis of Static Structure and Viscosity and Quantitative Testing of the Mode−Mode Coupling Approximation

The static structure of salt-free solutions of spherical polyelectrolytes, as determined by light scattering, is used as an input in the mode−mode coupling polyelectrolyte theory introduced by Hess and Klein and used to calculate the concentration-dependent solution viscosity of the same solutions....

Beschreibung
Zusammenfassung:The static structure of salt-free solutions of spherical polyelectrolytes, as determined by light scattering, is used as an input in the mode−mode coupling polyelectrolyte theory introduced by Hess and Klein and used to calculate the concentration-dependent solution viscosity of the same solutions. Quantitative agreement between measured and calculated values is obtained, underlining the appropriateness of the simplifications of the theory.
