Thickness and optical parameters of the adsorption polymer layers of polymethacrylic acid (PMAA) from water solution was investigated. Null-ellipsometry technique is used for in-situ determination of the adsorbed layer parameters. Two calculation methods are used for solving of the inverse ellipsometry problem for the suggested two-layer model of the surface. Adsorbed amount in the equilibrium state of the layers is calculated for the polymers with different molecular characteristics and corresponding adsorption isotherms are obtained.
Key words: ellipsometry, adsorption, polymethacrylic acid, surface layers
