Abstract

In the present study, the air-liquid surface and liquid-liquid interfacial activities of hydrophobically modified poly(vinyl alcohol) (PVA) solutions were investigated to determine the effects of NaCl concentration, polymer concentration, time, polymer molecular weight, polymer modification and the average length of the hydrophobic side groups. The hydrophobically modified PVA exhibit high air-liquid surface and liquid-liquid interfacial activities which increase with increasing NaCl concentration, polymer concentration, molecular weight and average length of the hydrophobic side groups. The observed strong dependence of surface and interfacial activities on salt concentration for this non-polyelectrolyte polymer is explained in terms of the reduced polymer solubility or salting out with increasing salinity.
