“…In the boundary layer, the density, the molecular mobility, and the properties associated with them change non-linearly through its thickness. Lipatov [3] established considerable increase in the density of polymers in thin adsorption layers, which then change into a layer with a looser packing and with a density lower than in the bulk of the polymer. The ratio of the contributions of these formations of different density in many ways determines the properties of the composite.…”
