Title:
スルホニルペンダント基を有するフッ素化コポリマー及びイオノマーの製造方法
Document Type and Number:
Japanese Patent JP7122254
Kind Code:
B2
Abstract:
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.
