A new method of synthesis of dispersed fluorescent polymer composites based on dispersion copolymerization of methylmetacrylate and styrene in the presence of quantum dots CdSe/CdS in supercritical carbon dioxide is suggested. A one-step scheme of the formation of fine particles of polymethylmetacrylate/polystyrene/CdSe/CdS composite is carried out and factors controlling their photoluminescent features and photochemical stability at long-term exposition under intense UV and sunlight irradiation on air are investigated.
