Turbidimetry of Two Aqueous Phase Emulsions and Related Systems
Abstract
Emulsion stability was studied using turbidimetry. the emulsions of interest contained one or more polymers. the first system studied was the two aqueous phase system made of a single solvent (water) and two polymers (polyethylene glycol and dextran). in the second and third systems, toluene was substituted for one of the phases and oil soluble polymer (polystyrene) was introduced. in all, efforts were made to choose nonadsorbing polymers, at least on a qualitative basis. Typical clearing times ranged from 1 2 to 1 h, although there were exceptions. All systems showed a second order response initially, indicating a flocculation controlled behavior. All explanations for the observed behaviors come from the conventional emulsion and thin film stability theory. © 1992.
