摘要：

Individual adsorption and simultaneous competitive adsorption from ternary solutions of uncharged polymers on aqueous dispersions of polystyrene lattices with different particle sizes were studied. The effects of the ratio of the polymers competing in simultaneous adsorption for the particle surfaces, and of the extent of the surface area available for the molecules, respectively, on the adsorption preference were investigated. Based on the experimental results, preferential adsorption parameters for polymers in pairs were established and used as a measure of the affinity of the macromolecules competing for the solid surfaces.
