On the Interaction Between Polyacrylamide and Anionic Surfactants
Abstract:
The interactions between anionic surfactants(sodium laurate(C11H23COONa), sodium dodecyl sulfonate(C12AS)) and polyacrymide have been investigated by measurements of the reduced viscosity and ultra-violet spectra of the polymeric solutions. The results showed that in neutral and weak acid solutions PAM formed an aggregate with C11H23COONa behaved as a polyelectrolyte through hydrogen bonding and there was a large amount of charges in the PAM main chain caused by aggregate. However, PAM-C12AS aggregate was formed through dipolar interactions only in the case when the concentration of C12AS was higher than critical micelle concentration.
