摘要： To provide a process for producing a liquid composition capable of forming a polymer electrolyte membrane of which breakage at the time of drying is suppressed; a process for producing a catalyst layer-forming coating liquid capable of forming a catalyst layer of which breakage at the time of drying is suppressed; and a method for producing a membrane/electrode assembly by which a catalyst layer or a polymer electrolyte membrane of which breakage at the time of drying is suppressed, can be formed.
A process for producing a liquid composition, which comprises holding a fluorinated polymer having -SO 2 F groups at from 110 to 130°C for at least 45 minutes; cooling the fluorinated polymer having -SO 2 F groups held at from 110 to 130°C to less than 110°C; converting the -SO 2 F groups in the fluorinated polymer having -SO 2 F groups cooled to less than 110°C to ion exchange groups thereby to obtain a fluorinated polymer having ion exchange groups; and mixing the fluorinated polymer having ion exchange groups and a liquid medium.

摘要： The present invention provides a fluorinated ionomer [polymer (I)] comprising recurring units derived from at least the following monomers: (i) 5 to 50% by weight of a fluorinated monomer [monomer (A)] containing at least one —SO2X functionality, preferably having the formula of CF2═CF—O—(CF2CF(CF3)O)m—(CF2)mSO2X (I) wherein m is 0 or 1, n is an integer between 0-10, and X is selected from F, OH, and O−Me+, wherein Me+ indicates an alkali metal ion or an ammonium cation of formula NR4− where each R independently represents a hydrogen atom or a monovalent organic radical selected from aliphatic radicals having from 1 to 8 carbon atoms and arylic or alicyclic radicals having from 3 to 8 carbon atoms; (ii) a non-functional fluorinated monomer [monomer (B)] having at least one ethylene unsaturation; and (iii) a fluorinated polyfunctional compound having the general formula: (CR1R2═CFCF2—O)a—Rf—((O)c—CF═CR3R4)b (II) wherein: a is an integer equal to or larger than 1, preferably a is 1, 2, or 3; b is 0 or 1 and the sum of a and b is an integer equal to or larger than 2; c is 0 or 1; R1, R2, R3 and R4 are independently selected from F, H, alkyl, alkoxy, polyoxy alkyl, perfluoroalkyl, perfluoroalkoxy or perfluoropolyoxy alkyl, preferably F; and Rf represents a hydrocarbon or fluorocarbon group having at least two carbon atoms. The low-EW perfluorinated ionomers made of polymer (I) are adapted to be processed into thin films, which are found to have superior physical stability than the existing products and are thus well suited for low humidity or high temperature electrochemical applications. Moreover, these low-EW ionomers are melt processable and have limited loss of volatile substances at their melt processing temperatures.
