The interaction of cationic surfactants from the series of dimethylbenzylalkylammonium chlorides (DMBAAC, alk. = C n H 2 n +1 ( n = 10, 12, 14)) with water‐soluble copolymers of N ‐vinyl‐2‐pyrrolidones (VP) with methacrylic, acrylic, and crotonic acids in aqueous and aqueous‐salt solutions was investigated by polarized luminescence. It was established that the main factors determining the stability of water‐soluble DMBAAC complexes with carboxyl‐containing VP copolymers include the composition and structure of the copolymer, the length of the alkyl group of DMBAAC, the ratio of the interacting components, the pH, and the ionic strength of the solution. The equilibrium dissociation constants of these complexes in aqueous solution were determined. Potentiometric titration, turbidimetry, and viscometry showed that the complexation features manifested by the interaction of individual DMBAAC's with carboxyl‐containing VP copolymers are also characteristic of complexation processes occurring with participation of industrial DMBAAC, which is a mixture of individual DMBAAC's.
