Abstract
The results obtained from Fourier transform infrared study of sodium dodecyl sulfate (SDS) in water and in the presence of styrene/acrylic acid (S/AA) copolymer are presented. The C-H stretching band of the SDS hydrocarbon tail at 2929 cm<sup>−1</sup> and the O-H stretching of H<sub>2</sub>O are sensitive to changes in the SDS concentrations. With the increasing concentration both bands are shifted to lower frequency. A mutual presence of S/AA copolymer and surfactant in the aqueous solution leads to a splitting of the bands due to COO<sup>−</sup> groups. It is proposed that the splitting is due to interactions between COO<sup>−</sup> segments of the copolymer and the "surfaces" of micelles through the Na<sup>+</sup> or Li<sup>+</sup> ions.
