Complexation of poly(N,N-dimethyl-N-benzyl-N-methacryloyloxyethyl)ammonium chloride with oppositely charged amphiphilic compounds was studied. The solubility and hydrodynamic properties of the resulting complexes in chloroform, methanol, and chloroform-hexane and chloroform-toluene mixtures were determined.
