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., CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 SO.sub.2 F. 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.
多氟卡波尼尔化合物,如多氟酮或多氟羧酸氟化物与氟离子和多氟烯基氯化物、溴化物或氟代磺酸盐反应,产生多氟烯氧基羧酸氟化物或磺酰氟,例如CF.sub.2 .dbd.CFCF.sub.2 OCF.sub.2 CF.sub.2 SO.sub.2 F。多氟烯氧基化合物与乙烯基不饱和单体(如四氟乙烯、氯三氟乙烯或偏氟乙烯)共聚,形成可塑性高的聚合物,在某些情况下具有导电性或可水润湿和染色性。
