| 520 | _ | _ | |a Ionic microgels are highly sensitive to changes in environmental conditions. This allows for controlling their size and effective interactions by adjusting the temperature, solvent quality, degree of polymer cross-linking, suspension ionic strength and particle concentration.In this work, we study theoretically the influence of the concentration-dependent de-swelling of weakly-crosslinked ionic microgels on structural and dynamic suspension properties. Our analysis is based on an effective interaction potential for ionic microgels derived by Denton [1], where we consistently introduce the de-swelling effect using the Denton-Tang method to compute the equilibrium microgel size [2]. Using the effective interaction potential, we compute pair correlation functions and static structure factors, which in turn are used as input for the calculation of dynamic suspension properties. The latter include hydrodynamic functions, collective diffusion coefficients, and the low- and high-frequency viscosities. We present and discuss results for the dependence of structural and dynamic properties on salt and microgel concentrations and on bare microgel charge. References[1] A. R. Denton, Phys. Rev.
