Abstract
Complexation between anionic, cationic ionomers as oil-soluble amphiphilic copolymers and various oil-soluble surfactants proceeds in dilute ionomer solution in THF, m-xylene and chloroform with surfactant molecules of various degree of aggregation as well as with surfactant reversed micelles containing water. Sulfonated polystyrene or styrene-N-ethyl-4-vinylpyridinium bromide copolymers were used as ionomers, while sodium bis(2-ethylhexyl) sulfos-uccinate, octadecyltrimethylammonium bromide, and primary aliphatic amines were used as surfactants. The formation of ionomer–surfactant complexes with well-defined limiting compositions (􀀁) is established. The value of 􀀁 depends on the nature of the ionomer salt:acid group, the aggregation state of the surfactant, the type of low-polarity solvent, and the chemical nature of the surfactant. The character of the ionomer–surfactant complexa-tion reaction and the structure of the new polymer–colloidal complexes are discussed.
