The phase behavior of a model athermal polymer-colloid suspension over a wide range of size asymmetry, colloid volume fraction, and polymer concentration was experimentally studied. The primary equilibrium finding is that based on cp/cp* as a dimensionless measure of polymer-induced depletion attractions, the suspension miscibility monotonically improves as the size asymmetry ratio Rg/R increases.
