Abstract

A modified method for estimating polyvinyl alcohol (PVA) in solution has been developed based on the principle of formation of PVA-iodine complex which has a characteristic absorption maxima. The amount of PVA adsorbed on the oil globules in liquid paraffin oil-water emulsions prepared by the polymer was determined. This was found to be dependent on the concentration of the polymer in the continuous phase of the emulsion until it reached a saturation point. Beyond that concentration, the amount of adsorption remained steady.
