Impregnation of polymer films (polyarylate DV, polymethylmetacrylate, chitosane, etc.) with some anthraquinone and azobensene dyes from their solutions in supercritical carbon dioxide (SC-CO₂) is investigated on qualitative level. Quantitative measurements are carried out with disperse dye Red 13 and polyarylate DV (PAR). The effect of pressure at temperatures ranged from 35 to 40 °C on the dye solubility in SC-CO₂ is studied by UV-spectroscopy. It is shown that at 35 °C and 13.8 MPa the dye concentration in PAR can reach 0.2 wt. % (2.8·10^-5 mol/l). Kinetic curve of Red 13 diffusion from SC-CO₂ solution into PAR matrix at 40 °C and 10 MPa has a monotonic character with saturation. The experimental results are analyzed in the framework of the theoretical model that implies a low solubility of functional additive (in this case dye) in a transportation fluid (SC-CO₂).
