Synthesis of perfluoropoly(ethylene glycol) ethers: CF3–[O–CF2–CF2]n–O–Rf(Rf= CF3 or C2F5; n= 1–5)
Abstract
A new synthetic method for the preparation of high molecular weight fluorocarbon ethers has been developed; polyethylene oxide was caused to react with elemental fluorine under conditions carefully regulated to fragment and perfluorinate the polyether system and yield a number of new fluorocarbon ethers.
