Abstract
Przedmiotem zgłoszenia są monodyspersyjne fluorescencyjne mikrosfery polimerowe, zawierające matrycę polimerową oraz znacznik fluorescencyjny, cechujące się tym, że matrycę polimerową stanowi kopolimer zbudowany z co najmniej dwóch różnych monomerów, korzystnie kopolimer poli(styren-co-akrylonitryl), zwłaszcza zawierający 10 - 90% wagowych akrylonitrylu i 10 - 90% wagowych styrenu, korzystnie 50 - 85% wagowych akrylonitrylu i 15 - 50% wagowych styrenu, zaś w matrycy polimerowej znajduje się znacznik fluorescencyjny, który korzystnie jest trwale, chemicznie wbudowany w matrycę polimerową i równomiernie w niej rozproszony. Rozmiar mikrosfer według wynalazku zawiera się w przedziale 0,1 - 20 µm, korzystnie w przedziale 1 - 3 µm, a ich temperatura topnienia jest wyższa niż 130°C, korzystnie wynosi powyżej 145°C. Zgłoszenie obejmuje także sposób syntezy monodyspersyjnych fluorescencyjnych mikrosfer polimerowych, polegający na tym, że prowadzi się kopolimeryzację monomerów wchodzących w skład wyżej określonej matrycy polimerowej wspólnie ze związkiem organicznym wykazującym fluorescencję, wykorzystywanym jako znacznik fluorescencyjny, korzystnie metodą kopolimeryzacji dyspersyjnej styrenu, akrylonitrylu oraz odpowiedniego znacznika fluorescencyjnego, w obecności stabilizatora oraz inicjatora reakcji, w rozpuszczalniku polarnym, korzystnie bezwodnym, w atmosferze obojętnej, korzystnie argonu lub azotu.The subject of the application are monodisperse fluorescent polymer microspheres containing a polymer matrix and a fluorescent label, characterized in that the polymer matrix is a copolymer composed of at least two different monomers, preferably a poly (styrene-co-acrylonitrile) copolymer, especially containing 10 - 90% by weight acrylonitrile and 10-90% by weight styrene, preferably 50-85% by weight acrylonitrile and 15-50% by weight styrene, while the polymer matrix has a fluorescent label that is preferably permanently chemically embedded in the polymer matrix and evenly dispersed in it. The size of the microspheres according to the invention is in the range of 0.1-20 Pm, preferably in the range of 1-3 Pm, and their melting point is higher than 130 ° C, preferably above 145 ° C. The application also includes a method for the synthesis of monodisperse fluorescent polymer microspheres, in which the monomers included in the above-defined polymer matrix are copolymerized together with a fluorescent organic compound used as a fluorescent label, preferably by dispersion copolymerization of styrene, acrylonitrile and the appropriate fluorescence label in the presence of a stabilizer and a reaction initiator, in a polar solvent, preferably anhydrous, in an inert atmosphere, preferably argon or nitrogen.
