Abstract: The process is described for recycling a heat-treated solid article including a fluorinated polymer having a fluorinated polymer backbone chain and a plurality of groups represented by formula —SO3Z, wherein Z is independently a hydrogen, an alkali-metal cation, or a quaternary ammonium cation. The heat-treated solid article was previously heated at a temperature of at least 100° C. The process includes heating the heat-treated solid article in the presence of water and base to form a fluorinated polymer salt solution, allowing the fluorinated polymer salt solution to cool, and converting the fluorinated polymer salt solution to fluorinated polymer solution wherein Z is hydrogen by cation exchange.

Abstract: The process produces a fluorinated olefin from a fluorinated copolymer having at least one of sulfonic acid groups, carboxylic acid groups, or salts thereof. The process includes heating the fluorinated copolymer at a first temperature not more than 450° C. to decompose at least one of the sulfonic acid groups, carboxylic acid groups, or salts thereof to form a partially pyrolyzed intermediate and subsequently heating the partially pyrolyzed intermediate at a second temperature of at least 550° C. to produce the fluorinated olefin.
