Title:
A sulfur content aromatic series Alekan monomer fluorinated and sulfonated
Document Type and Number:
Japanese Patent JP6112676
Kind Code:
B2
Abstract:
A sulphur-comprising, fluorinated and sulphonated aromatic alkane monomer which can be used for the manufacture of a polymer membrane intended, for example, for a PEM (Polymer Electrolyte Membrane) fuel cell, said functionalized monomer corresponding to formula: (I) F-Ar1-X1-(CH2)n-X2-Ar2-F in which: -n is included in a range from 1 to 20; -the symbols X1 and X2, which may be identical or different, are S, SO or SO2; -the symbols Ar and Ar2, which may be identical or different, are a phenylene group, at least one of which bears a sulphonic group -SO3H or a sulphonate group -SO3M, wherein M is an alkali metal cation.
