000874670 520__ $$aMicrogels are solvent-containing, cross-linked polymer networks of colloidal size that can reversibly swell or deswell in response to external stimuli. Ionic microgels in particular are highly sensitive to changes in environmental conditions such as temperature, solvent quality, polymer cross-linking, suspension ionic strength and particle concentration, which allows for controlling their size and effective interaction. In this work, we study theoretically the effects of concentration-dependent de-swelling of weakly-crosslinked ionic microgels on structural and dynamic suspension properties [1]. We use and compare two different theoretical approaches, namely the Denton-Tang method based on a Poisson-Boltzmann cell model [2] and a thermodynamic perturbation method [3], to calculate the equilibrium microgel size. The state-dependent microgel size is a salient ingredient to the effective interaction potential for spherical ionic microgels derived by Denton [4] which underlies our calculation of  static pair correlation functions and structure factors. The latter static quantities are used as input in our calculation of dynamic suspension properties including the  hydrodynamic function, collective diffusion coefficient, and low- and high-frequency viscosities. For a quantitative assessment of de-swelling effects, results for static and dynamic suspension properties are compared with corresponding findings for a reference suspension having constant microgel size.
