Abstract
The complex formation reactions of polyvinyl ether of diethylene glycol as well as vinyl ether of diethylene glycol–vinyl butyl ether copolymers with polyacrylic acid have been studied in aqueous and alcohol solutions The formation of interpolymer complexes which were stabilized by hydrogen bonds was shown The effects of molecular weight of polyacrylic acid and the nature of the nonionic polymer on the composition and stability of interpolymer complexes were clarified The critical pH values of complexation were determined for different systems with various molecular weights and hydrophobic–hydrophilic balances The stability of the interpolymer complexes formed in aqueous and alcohol solutions with respect to dimethylformamide addition was evaluated The role of hydrophobic interactions and the presence of active groups on stability of the interpolymer complexes is discussed
