The dissolution of water‐insoluble polymers in the surfactant solution. The polyelectrolyte‐like behavior of the dissolved polymers

Abstract

Polymers, such as polyvinyl formal (PVF) and polyvinyl acetate (PVAc), which are insoluble in water, dissolved in anionic surfactant solution. Polymer solutions of PVF, PVAc, and polyvinyl alcohol in surfactant were studied viscometrically and electrophoretically. The polymer forms a complex with the surfactant, the behavior of which is similar to that of polyelectrolyte. The complex is negatively charged and migrates to the anode. With dialysis of the solution of polymer‐surfactant complex against running water, the polymer separates out; however, the polymer does not separate out of undialyzed solution, even if the solution is diluted to far less concentration than the CMC of the surfactant. Thus the dissolution of the polymers in the surfactant solution is due to the oriented adsorption of surfactant ions on the polymer molecule. The amount of adsorbed surfactant ions was estimated. The adsorption might be of the Langumuir type.

Polymer/surfactant interaction—Its relevance to detergent systems

“…Because of the association of polymers and surfactants in solution, it would not be surprising if they could influence each other's solubility, as well as that of a third component. Indeed, it has been found that SDS, for example" can actually solubilize certain normally insoluble polymers, such as polyvinylacetate" as demonstrated by Isemura and Imanishi (62). Similar work had been carried out earlier by Sata and Saito (63).…”

The interaction of polyvinylpyrrolidone with aromatic compounds in aqueous solution Part IV. Evaluation of the co-operativity parameter, and the methylene-group contribution to the binding strength, for the alkyl parahydroxybenzoates

“…These relatively large site-sizes are in fact not confined to cosolute binding by PVP, but have been observed in other polymer/ cosolute binding systems such as p01y(vinyl alcohol)/sodium dodecyl sulphate (33) and polyacrylate/aromatic quaternary ammonium compounds (34).…”

Effect of the properties of coal surface and flocculant type on the flocculation of fine coal

“…The polymer can be dissolved in a solution of surfactant, thereby creating a soluble ion complex of surfactant and organic polymer. (Isemura and Imanishi, 1958).…”
