The interaction of fluorocarbon containing hydrophobically modified polyelectrolyte (FMPAANa) with two kinds of non‐ionic surfactants (hydrogenated and fluorinated) in a semidilute (0.5 wt%) aqueous solution had been studied by rheological measurements. Association behavior was found in both systems. The hydrophobic interaction of FMPAANa with fluorinated surfactant (FC171) is much stronger than that with hydrogenated surfactant (NP7.5) at low surfactant concentrations. The interaction is strengthened by surfactants being added for the density of active junctions increased. Whereas distinct phenomena for FC171 and NP7.5 start to be found as the surfactants added over their respective certain concentration. The interaction of polyelectrolyte with fluorinated surfactant increases dramatically while that with hydrogenated surfactant decreases.
