Abstract
A dilute suspension of ordered polymercolloid particles was investigated by static and dynamic light scattering. The obtained results are compared with a Brownian dynamic (BD) simulation of a model system consisting of hard spheres interacting with an exponentially screened Coulomb potential. The long time properties of the self‐ and collective correlation functions are investigated in detail. The obtained mean squared displacement is best described by a stretched exponential model and the collective long time diffusion from the BD simulation can only be approximately described by a kinetic theory based on a hard sphere system.Keywords
