Abstract

a. Procédé de transformation par fusion de polymères fluorés. b. On effectue une transformation par fusion d'un polymère fluoré qui contient des groupes fonctionnels pendants tels que des groupes acides sulfoniques, acides carboxyliques, en présence d'un milieu aqueux qui améliore la caractéristique d'écoulement à l'état fondu du polymère. c. Réparation des diaphragmes en électrolyse.
