Summary The interaction of polyelectrolytes with ionic surfactants is studied by turbidimetry and electron micrography. The turbidity of the mixed solution of PVS (poly(vinyl sulfate)) and CTAB (cetyltrimethylammonium bromide) showed a sharp maximum at the mole ratio of 1∶1, indicating quantitative binding between PVS and CTAB. A multilayer structure was observed on the electron micrograph only at the mole ratio of PVS:CTAB=2∶1 with a spacing of about 25A. At the mole ratio of PVS:CTAB=1∶1, a single strand structure was observed. The system of ionene polymer (3,4) $$\left( {\begin{array}{*{20}c} + \\ {\text{N}} \\ \end{array} {\text{CH}}_{\text{2}} )_3 - \begin{array}{*{20}c} + \\ {\text{N}} \\ \end{array} {\text{CH}}_{\text{2}} )4} \right)$$ -SDS (sodium lauryl sulfate) forms a multilayer structure at the equivalent ratio of 1∶1 with a spacing of 20A.
