Zusammenfassung:	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 to form a fluorinated polymer solution. L'invention concerne un procédé qui est destiné au recyclage d'un article solide traité thermiquement comprenant un polymère fluoré ayant une chaîne principale de polymère fluoré et une pluralité de groupes représentés par la formule -SO3Z, Z représentant indépendamment un atome d'hydrogène, un cation de métal alcalin ou un cation d'ammonium quaternaire. L'article solide traité thermiquement a été préalablement chauffé à une température d'au moins 100 °C. Le procédé comprend le chauffage de l'article solide traité thermiquement en présence d'eau pour former une solution de polymère fluoré.
