通过氟代烷酰基过氧化物与含低聚氧乙烯单元的乙烯基硅烷（或甲基丙烯酸酯）以及丙烯酸、二甲基丙烯酰胺和异丙基丙烯酰胺等共聚单体反应，制备了新型含低聚氧乙烯单元的氟烷基化封端共聚低聚物。通过这些含低聚（oxidase）单元的氟化共低聚物，可以有效地降低水的表面张力，具有类似于CMC的清晰的断裂点，并且似乎在水中形成类似于胶束的分子内或分子间聚集体。结果表明，该齐聚物对金属离子具有良好的萃取性能，含LiCF_3SO_3的齐聚物电解质膜在室温下具有4×10 ~（-5）S/cm的离子电导率。特别令人感兴趣的是发现含有寡聚（oxidase）单元的氟烷基化封端的丙烯酸共低聚物在体外强烈且选择性地抑制HIV-1复制。
New fluoroalkylated end-capped co-oligomers containing oligo (oxyethylene) units were prepared by reactions of fluoroalkanoyl peroxides with oligo (oxyethylene) units -containing vinylsilane (or methacrylates) and co-monomers such as acrylic acid, dimethylacrylamide and isopropylacry-lamide. By these fluorinated co-oligomers containing oligo (oxyethylene) units, the surface tension of water could be reduced effectively with a clear break point resembling CMC and appeared to be formed intra- or inter molecular aggregates resembling micelles in water. The co-oligomers containing oli-go (oxyethylene) units were found useful for extracting various metal cations and oligomer electrolyte film containing LiCF3SO3 showed high ionic conductivity of 4×10-5S/cm at room temperature. Of particular interest is the finding that the fluoroalkylated end-capped acrylic acid co-oligomers containing oligo (oxyethylene) units were found to strongly and selectively inhibit HIV-1 replication in vitro.
