Abstract
The interaction of polyelectrolytes with oppositely charged ionic surf actants was studied at low surfactant concentrations using photochemic al bound and free probes. Free probes migrate to initially formed pre- aggregates in systems with high charge-density polyelectrolytes, givin g rise to excimer emission. For these systems the initial aggregation process seems to be due to electrostatic interactions. For huger surfa ctants or copolymers containing larger proportions of neutral monomer that interactions are of hydrophobic nature.
