Synthesis and polymization of acrylate containing perfluoronineyl were investigated. N-methyl-N-p-perfluorononenoxybenzenesulfamidethyl acrylate (III) was synthesized from p- perfluorononenyloxybenzenesulfonyl chloride by amidation and esterification. The optimum conditions of esterification was n(II):n(Acryloyl chloride)=1:3, react at room temperature for 6h, The yield of III was 75.0 %. The fluorinated copolymer emulsion with blue-fluorescence was synthesized by semicontinuous emulsion polymerization of III initiated by K2S2O8 with butyl acrylate (BA), methyl methacrylate (MMA). Acrylate (III) and copolymer film were characterized by FT-IR,1HNMR and ESI-MS respectively. The copolymers emulsion stability and content of III in copolymer on the water contact angle on the copolymer film were studied. When the film contains 20 % III in weight, the water contact angle on the film is 88.2?
