The cellulose derivatives solutions in the presence of surfactants have been investigated by the enhanced Rayleigh scattering (ERS) technique. The ERS experiments yield different information on the aggregate formation of cellulose derivative/surfactant in aqueous solution on the basis of theory of ERS. The results indicated that the ERS intensity of polymer/surfactant system changes in different ways with continuing addition of surfactant. The critical aggregate concentration of cellulose derivative/surfactant systems is easy to determine. The change of ERS intensity reveals the aggregate formation of polymer/surfactants and the shrinking state of polymer chains in evidence. Accordingly, ERS is a potent technique to study the cellulose derivative solutions in the presence of surfactants due to its simplicity, rapidity and sensitivity.
