摘要
The modification of hydroxytelechelic poly(ethylene oxide)s (PEO) of molecular weights 10.000, 20.000 by a fluorinated acid leading to fluoroacylated poly(ethylene oxide)s (FA-PEO) is described. The one pot process involving the in situ generation of a fluorinated anhydride by reaction with N,N-dicyclohexylcarbodiimide (DCC) leads to complete modification of hydroxy end-groups. The reaction is catalyzed by dimethylaminopyridine (DMAP). A method, based on F-19-NMR spectroscopy, has been developed for the detection and titration of residual PEO hydroxy end-groups.
