    摘要： A process for the preparation of cross-linked fluorinated polymers comprising sulfonic acid functional groups comprising the steps of: a) providing at least one fluorinated polymer (P) comprising at least one —SO3M functional group and less than 2% of —SO2F functional groups with respect to the total amount of —SO3M and —SO2F functional groups, wherein each M is selected from H and alkaline metals; and b) reacting said fluorinated polymer with at least one cross-linking agent of formula R(X)n under conditions that promote the formation of covalent bonds between the at least one functional group —SO3M of fluorinated polymer (P) and at least one functional group X of the cross-linking agent.

    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.
