摘　　要：以聚乙二醇单甲醚(MPEG)为原料,与2-溴异丁酰溴经酯化反应合成了端基为溴原子的MPEG-Br;以MPEG-Br为大分子引发剂,甲基丙烯酸十二氟庚酯经电子活化再生原子转移自由基乳液聚合法合成了新型的含氟两亲性嵌段聚合物(1)乳液,其结构经1H NMR,IR和X-射线光电子能谱(XPS)表征。接触角测量结果表明:1可改变岩心的润湿性,由强液湿转变为气湿。A novel fluorine-containing amphiphilic block copolymer（1） emulsion was synthesized by atom transfer radical polymerization of dodecafluoroheptyl methacrylate using MPEG-Br as the activator which was prepared by esterification of MPEG with 2-bromoisobutyryl bromide. The structure was characterized by1 H NMR,IR and X-ray photoelectron spectroscopy（XPS）. The results of contact angle（CA） analysis showed that the emulsion of 1 could change the wettability of rock from strong liquid-wetting to gas-wetting.
