The interaction of cationic and anionic type of surfactants with nonionic temperature-responsive polymer hydrogels accompanied by a significant changes in their swelling parameters were shown. Comparatively under low concentrations of surfactant in the surrounding solution the swelling degree of the product of interaction decreases and vice versa. It is due to the fact that at relatively low concentrations of surfactant the hydrophobic interactions lead to the formation of additional physical cross-linking nodes, while at high the conversion of nonionic network into polyelectrolyte hydrogel takes place. The indicated factors allow to carry out regulation the phase transition temperature of this type of hydrogel by surfactants as well.
