In the present work the results of the studies on the effect of surface active-agents and polymers on a mean film thickness have been presented. The experimental studies on mean thickness of a film of water and aqueous solutions of hexadecyltrimethylammonium bromide HTAB and polyacrylamide flowing down the hydrophobic organic glass plate, have been carried outIt was stated that the reduction of the film thickness is observed when the shear induced structures of a polymer and surfactant are present in a solution. The best results were obtained for aqueous solutions of HTAB with addition of sodium salicylate.
