| 摘 要： | 研究了含全氟壬烯基丙烯酸酯的合成及其聚合反应。以全氟壬烯氧基苯磺酰氯为原料,经酰胺化、酯化得到N-甲基-N-p-全氟壬烯氧基苯磺酰胺基乙基丙烯酸酯(Ⅲ);确定了Ⅲ的较优合成工艺条件为:n(Ⅱ)∶n(丙烯酰氯)=1∶3,室温反应6 h,含氟单体Ⅲ的收率为75.0%;并将Ⅲ与甲基丙烯酸甲酯(MMA)、丙烯酸丁酯(BA)在K2S2O8(KPS)存在下,通过半连续乳液聚合法,制备了含氟丙烯酸酯乳液。用傅里叶变换红外光谱(FTIR)、核磁共振波谱(1HNMR)、质谱(ESI-MS)等对含氟丙烯酸酯单体(Ⅲ)和聚合物乳胶膜的结构进行了表征;考察了乳液的稳定性、Ⅲ的含量对聚合物膜上水接触角的影响。当含氟丙烯酸酯占单体总质量的20%时,水接触角为88.2°。

| Abstract: | 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? |
