STUDY OF THE STRUCTURE OF ADSORBED SURFACE-FILMS OF POLY(METH)ACRYLATES BY WETTING METHOD

Monomacromolecular films of poly(co)methacrylates of linear and anchor ing structure formed at the surface of aluminum foil during polymer ad sorption from solution were studied by wetting with two liquids (water or glycerol). Such films are permeable for the wetting liquid, which is in partial contact with the substrate surface. An additive model wh ere the substrate-polymer wetted system is considered as a planar hete rogeneous surface was proposed to evaluate quantitatively the substrat e structure of adsorbed surface layers. This model was used to estimat e the parameters of the polymer layer: the fraction of segments attach ed to the surface, porosity, and film thickness. The obtained paramete rs were applied to analyze the relationship between copolymer nature a nd film structure.
