Abstract
The reaction of a polyfluorocarbonyl compound such as a polyfluoroketone or polyfluorocarboxylic acid fluoride with fluoride ion and a polyfluoroallyl chloride, bromide or fluorosulfate produces a polyfluoroallyloxy carboxylic acid or ester, e.g., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 COOH. 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.
