Monoprotected polyethylene glycols (PEG) react with epichlorohydrin to furnish PEGylated epoxides. The latter were converted into the corresponding α‐(2‐F‐alkylethyl)thiomethyl polyethylene glycols by treatment with 2‐F‐alkylethanethiol. Surface activity of the obtained surfactants was investigated by evaluation of PEG and perfluoroalkyl chains length on the critical micelle concentration (CMC), surface
单保护的聚乙二醇(PEG)与环氧氯丙烷反应生成聚乙二醇化的环氧化物。通过用2- F-烷基乙硫醇处理将后者转化为相应的α-(2- F-烷基乙基)硫代甲基聚乙二醇。通过评估PEG和全氟烷基链长对临界胶束浓度(CMC),表面和界面张力的影响,研究了所得表面活性剂的表面活性。
