ABSTRACT OF THE DISCLOSURE The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride or fluorosulfate produces a polyfluoroallyloxy compound, e.g., CF2=CFCF2OCF2CF2SO2F. The polyfluoroallyloxy compounds copolymerize with ethylenically unsaturated monomers such as tetrafluoroethylene, chlorotrifluoroethylene or vinylidene fluoride to form polymers which are moldable, and in some cases electrically conducting or are water- wettable and dyeable.
