| Abstract: | 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 and interfacial tensions. |
