| Abstract: | ABSTRACT The effect of polymer volume concentration C, pH and ionic strength (NaCl concentration, CNal) of solution, polymer molecular mass, acetate groups' content in a polymer chain, and ethanol concentration on the stability of microscopic emulsion films (MEF) stabilized with the adsorption layers of poly(acrylic acid) (PAA) and acrylic acid-vinylacetate copolymers (PAA-VA) has been studied. The kinetics of MEF thinning under the conditions when two heptane drops in a polymer solution are brought into contact and pressed with a permanent force has been studied. The free energy ? F of interaction in the film has been evaluated on the basis of measuring the film thickness Hf by photometry and determining the film profile in the Plateau region. |
