Abstract: Method of producing purified fluoropolymers comprising repeat units of tetrafluoroethylene and a fluoro-olefin comprising SO3- groups are described. In a first step, an unpurified aqueous dispersion of the fluoropolymer, including the counter-cations of the SO3- groups, is subjected to cation exchange. This cation-exchanged dispersion is then subjected to ultrafiltration. The resulting purified dispersions and fluoropolymers contain low levels of both cations and anions. Articles prepared from such purified fluoropolymers are also described.

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.
