Title (EN) FLUORINATED COPOLYMER HAVING SULFONYL PENDANT GROUPS AND METHOD OF MAKING AN IONOMER
(FR) COPOLYMÈRE FLUORÉ PRÉSENTANT DES GROUPES PENDANTS SULFONYLE ET PROCÉDÉ DE PRODUCTION D’UN IONOMÈRE
Abstract:
(EN) The copolymer includes divalent units represented by formula: (I), one or more independently selected fluorinated divalent units, and -SO2X end groups. In this formula, b is 2 to 8, c is 0 to 2, and e is 1 to 8. In each SO2X, X is independently F, -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)aSO2NZ]1-10SO2X', or -OZ, wherein Z is a hydrogen, an alkali-metal cation or a quaternary ammonium cation, X' is independently -NZH or -OZ, and each a is independently 1 to 6. The copolymer has an -SO2X equivalent weight of up to 1000. The method includes copolymerizing components including fluorinated olefin and a compound represented by formula CF2=CF-CF2(O-CbF2b)c-O-(CeF2e)-SO2X', wherein b, c, and e are as defined above. A method of making a membrane using the copolymer or ionomer is also provided. A polymer electrolyte membrane that includes the copolymer or the ionomer and a membrane electrode assembly that includes such a polymer electrolyte membrane are also provided.
(FR) L’invention concerne un copolymère comprenant des unités divalentes représenté par une formule (I), une ou plusieurs unités divalentes fluorée choisies indépendamment, et des groupes terminaux -SO2X. Dans cette formule, b est compris entre 2 et 8, c est comprise entre 0 et 2, et e est comprise entre 1 et 8. Dans chaque SO2X, X est indépendamment F, -NZH, -NZSO2(CF2)1-6SO2X', -NZ[SO2(CF2)aSO2NZ]1-10SO2X', ou -OZ, Z étant un hydrogène, un cation métallique alcalin ou un cation d’ammonium quaternaire, X’ étant indépendamment -NZH ou -OZ, et chaque a est compris indépendamment entre 1 et 6. Le copolymère présente un poids équivalent de -SO2X allant jusqu’à 1 000. Le procédé comprend des constituants de copolymérisation comportant une oléfine fluorée et un composé représenté par une formule CF2=CF-CF2(O-CbF2b)c-O-(CeF2e)-SO2X', b, c, et e étant chacun tel que défini ci-dessus. L’invention concerne également un procédé de préparation d’une membrane au moyen du copolymère ou du ionomère. L’invention concerne en outre une membrane électrolyte polymère qui comprend le copolymère ou l’ionomère et un ensemble électrode à membrane qui comprend une telle membrane électrolyte polymère.
