Our previous model of colloidal stability of a system containing aggregates composed of several fine colloidal particles attached to a single, very long polymer chain [1] is extended to include the nonuniform distribution of particles among macromolecules. Both the reversible and irreversible polymer - particle attachment was considered. The predictions of the model are confronted with experimental results of the floccullation of silver iodide hydrosol by very-high-molecular weight polyacrylamide.
