Abstract

Bicomponent monolayers of ethylene oxide-propylene oxide block copolymer (I) and polypropylene glycol (II) with stearic acid (III) or cetyl alcohol (IV) were studied at the air-water (40% NaNO3) interface by the compression isotherms at 20? The experimental data were analyzed in terms of the mol.-area additivity rule and the 2-dimensional phase rule. I was immiscible with III but miscible with IV while II was immiscible with both III and IV.
