[CH3:1][N:2]([CH3:8])[C:3](=[NH:7])[N:4]([CH3:6])[CH3:5].S(OC)(O[CH3:13])(=O)=O>CN(C=O)C>[CH3:1][N:2]([CH3:8])[C:3](=[N:7][CH3:13])[N:4]([CH3:6])[CH3:5]Tetramethlguanidine functionalized perfluorinated polymers were further treated with dimethyl sulfate (DMS) in DMF at 90° C. for 24 hr. Pentamethylguanidine functionalized perfluorinated polymer was obtained. Guanidine functionalized perfluorinated polymers was further treated with 1 M NaOH followed by washing with water.
