In this work structure-dynamics relations in mixtures of highly charged, spherical polymer colloids are investigated. Experimental access is provided by light scattering experiments, that enable a selective determination of partial structure factors and intermediate scattering functions by index-matching. To adjust the refractive index of water/glycerol mixtures to that of the polymer particles, a new class of copolymer particles is developed as model system. Integral equations and Brownian Dynamics are employed for a theoretical description and compared to experimental light scattering data.<eng>
