Abstract
Copolymers of acrylic acid and vinylbutyl ether AA/VBE) have been involved in complexation reactions with non-ionic poly-N-vinylpyrrolidone (PVP), polyethylene glycol (PEG) and cationic poly-N-methyl-4-vinylethynylpiperidinol-4 (PVEP) and polyvinyl ether of monoethanolamine (PVEMEA) polymers. Interpolymer complexes (IPC) are stabilized due to the formation of either cooperative system of hydrogen or ionic bonds depending on the nature of interacting macromolecular components. The stoichiometry of IPC was determined by electrochemical methods. The stability of IPC depends on thermodynamic quality of the solvents, temperature, and degree of ionization. The permeability of IPC membranes with respect to urea was studied. Copyright © 2000 John Wiley & Sons, Ltd.
