General conditions of formation and dynamics of adsorption layer of inert surface‐active compounds at the polymer/gas interface were investigated. A quantitative model describing the behavior of surface‐active additive in polymer film during evaporation into gaseous phase was developed. The correctness of the model was demonstrated on the specific example of studying the behavior of fluoro‐organic compounds in polyethylene. The possibility of modifying surface properties of thermoreactive polymers by reactive surface‐active compounds was elucidated. It was found that the degree of epoxy polymer surface modification in systems made up of epoxy resin/monoepoxy ester of fatty acid is controlled by the ratio between the additive's rate of diffusion and the rate of its chemical reaction.
