Abstract
Colloidal suspensions with free polymer coils which are larger than the col loidal particles are considered. The polymer-colloid interaction is modeled by an extension of the Asakura-Oosawa model. Phase separation occurs into dilute and dense fluid phases of colloidal particles when polymer is added. The critical density of this transition tends to zero as the size of the p olymer coils diverges.
