Aggregation of fluoroalkyl units: synthesis of gelling fluoroalkylated end-capped oligomers containing hydroxy segments possessing metal ion binding and releasing abilities

Abstract

New fluoroalkylated end-capped oligomers containing 2-hydroxypropyltrimethylammonium or carboxy(hydroxy)- methylamido segments, which are prepared from the reaction of fluoroalkanoyl peroxides with the corresponding monomers, can cause gelation where strong aggregation of the fluoroalkyl segments is involved in establishing the physical gel network, not only in water but also in organic media under the non-crosslinked conditions, and had a high metal ion binding and releasing power.
