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. Quantitative agreement between measured and calculated values is obtained, underlining the appropriateness of the simplifications of the theory.
