摘　　要：采用不饱和的含氟单体与丙烯酸酯类单体在常压下反应合成核壳型含氟丙烯酸酯共聚物,并用其整理亚麻织物。采用傅里叶红外光谱仪、透射电子显微镜、X光电子能谱等分析手段研究了乳液及其胶膜的结构以及亚麻织物整理后应用性能的变化。结果表明:半连续种子乳液聚合法可合成出纳米级核壳结构的氟代丙烯酸酯共聚物乳液,用其整理亚麻织物,织物变得光滑平整。整理后的亚麻布样断裂强力明显提高,透湿透气性略有降低。胶膜对水和十六烷的接触角分别为98.32°和65.58°。The fluorinated acrylate copolymer was synthesized by the reaction of unsaturated monomer and acrylic monomer under normal pressure, and the linen fabric was finished with the fluorinated acrylate copolymer. The structures of the latexes and their films as well as the applied properties of flax fabrics after fin- ishing were studied by means of Fourier transform infrared spectroscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The results show that nanoscale fluorinated acrylate copolymer with core-shell structure could be synthetised by semi-continuous seed emulsion copolymerization. The finished fabric by the emulsion became smooth and flat. The tensile strength of the finished fabric was increased significantly. And water and air permeability decreased slightly. The contact angles of the films to water and hexa- decane were 98.32° and 65.58°, respectively.
