The interaction of polymers with surfactants
The interaction between a polymer coded 4364B, containing fluorinated side chains and amine oxide groups, and sodium dodecyl sulfate (SDS) in aqueous solution was studied. Also the interaction of cationic substituted cellulose ether, Polymer JR, with surfactants such as sodium dodecyl sulfate (SDS),...

The interaction between a polymer coded 4364B, containing fluorinated side chains and amine oxide groups, and sodium dodecyl sulfate (SDS) in aqueous solution was studied.

The surface tension of a solution containing the polymer and the surfactant in various molecular ratios was measured. The surface tension versus surfactant concentration curves at different polymer concentrations revealed that the polymer bound the surfactant in considerable quantities.
