Interpolymer complexes of some vinyl copolymers in a solution and on the boundary of two liquid phases

By electrochemical and spectroscopic methods the interaction of acrylic aci d and vinylbutyl ether, acrylic acid and styrene, vinyl ether of monoethano l amine and styrene copolymers with some anionic (polyacrylic and polymetha crylic acids) and cationic (polyvinyl ether of monoethanol amine and poly-N -methyl-4-vinylethynyl piperidole-4) polymers have been investigated in a s olution and on the boundary of two non-mixing liquids. The formation of int erpolymer complexes with exact composition occurs. Upon realization of comp lexation on the liquid-liquid boundary the complex formation reaction has s ome time, caused obviously by diffusion of interacting macromolecules to th e interface layer where the interaction takes place.
