Structure (1a) or (1b) [Chemical 1] (Wherein, Z is S, SO 2, or POR (wherein, R represents a linear or branched perfluoroalkyl group having a carbon atom may also be 1 to 14, which contain oxygen or chlorine optionally, 6 An aryl or substituted aryl group of -12 carbon atoms, or an alkyl of 1-8 carbon atoms); R F optionally contains oxygen or chlorine 1- It comprises a 20 linear or branched perfluoroalkene group of carbon atoms; Q is F, -OM, -NH 2, -N (M) SO 2 R 2 F, and -C (M) (SO 2 R 2 F ) 2, where M comprises H, an alkali cation, or ammonium; the R 2 F group comprises a perfluorinated or partially fluorinated alkyl, and optionally comprises an ether oxygen Even if And n is 1 or 2 for (1a) and n is 1, 2 or 3 for (1b). These monomers are used in the production of homopolymers and copolymers that are useful when producing polymer electrolyte membranes. Electrochemical cells, such as fuel cells, containing these membranes are also described. |
