ABSTRACT:
The invention provides a process for polymerizing hexafluoropropene oxide in a polymerization initiator solution to produce a fluorinated polyether. The initiator solution contains a polymerization initiator of the formula: CSOCF.sub.2 -Rf-CF.sub.2 OCs wherein Rf is a C1-C4 perfluoroalkylene group or a C2-C1O perfluoroalkylene group having an ether bond in a linear or cyclic hydrocarbon compound having at least 5 ether bonds in a molecule. An aprotic polar solvent having a melting point of lower than -40.degree. C. under atmospheric pressure is added to the initiator solution.
