Phosphonic acid polymer, method for producing the same, and electrolyte membrane for fuel cell |
| abstract |
A novel phosphonic acid polymer having high proton conductivity is provided. SOLUTION: Using dimethylphosphonate CHCF2PO (OEt) 2 as a source material, an intermediate compound HOCH2CF2PO (OEt) 2 is produced, and then the reaction between the intermediate compound and the compound H2C = CFCOCl is performed to obtain H2C = CFCOOCH2CF2PO (OEt) 2. A method for producing a phosphonic acid polymer comprising a molecular chain structure represented by Structural Formula (1) as a repeating unit, wherein the polymer is polymerized to form a polymer, and then the ethyl group of the polymer is substituted with hydrogen. [Selection figure] None |
