    摘要: Polyfluorodiacyl fluorides having the formulaFOC(CFXOCF.sub.2).sub.p (CF.sub.2).sub.n-1 (CF.sub.2 OCFX).sub.q COFwherein n represents an integer of 2 to 4; X represents fluorine or chlorine atom or trifluoromethyl group; p=0 to 5; q=0 to 5; p+q>1 are produced by reacting a perfluorolactone with a fluorocarbon epoxide, optionally in the presence of an aprotic polar solvent and a nucleophilic reagent.
