We report about synthesis and characterizations of thermoresponsive core-corona type nanosphere with controlled corona chain length. Nanospheres having PNIPAAm cilia with narrow polydispersity were prepared by copolymerization of PNIPAAm macromonomer and styrene. In addition, effect of PNIPAAm molecular weight on sphere diameters was investigated using SEM. As a result, PNIPAAm have important role as a dispersant. Finally, we investigated that dispersion stability of thermoresponsive nanospheres. Obtained nanospheres were colloidally stable at 20oC, but precipitated at 37oC.
