Meth acrylate copolymer latexes containing fluorine have been prepared via emulsion copolymerization of methyl methacrylate(MMA), butyl acrylate(BA) and fluorinated monomers, 2,2,2-trifluoroethyl methacrylate(TFEMA) and 2,2,3,3,4,4,4-heptafluorobutyl methacrylate(HFBMA). FT-IR,¹H NMR, ¹³C NMR and ¹⁹F NMR results confirmed the incorporation of fluorinated methacrylate units in the copolymers. The effect of amount of TFEMA, solubilization agent β-cyclodextrin, and polymerization conditions on the reaction rate, particle size and size distribution of latex, as well as on the copolymer properties have been investigated. The results indicated that the reaction rate increased with the increase of the reaction temperature in the range of 55 to 65℃. DSC and TGA results showed the reaction temperature hardly affected the copolymer composition. The contact angles of the copolymer films with fluorine were greater than that of the film without any fluorine moiety, suggesting that the fluorine-containing units in the copolymers are in favor of improvement of the film property.
