The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorcarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy carboxylic acid fluoride or sulfonyl fluoride, 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. |
