Presents experimental studies of kinetics, configuration, and hydrodynamic properties of adsorbed polymer chains at colloidal surfaces. Describes flocculation and stabilization of colloidal particles in solutions containing adsorbing or nonadsorbing uncharged polymers or polyelectrolytes. Highlights theoretical and computer simulation studies of the structure and dynamics of polymers adsorbed at interfaces. Discusses interactions of macromolecules with micelles, bilayers, liposomes, and proteins.
