    This paper deals with a Poly(arylene ether sulfone)copolymer which is a kind of component of the Fuel Cell and is a key element of the PEMFC. 3,3′-Sulfonated-4,4′dichlorodiphenyl sulfone (SDCDPS) is composited by 4, 4′-Dichlorodiphenyl sulfone (DCDPS) and Fuming sulfuric acid whose ratio is 1 : 3.3 and is derived from Elec trophilic Sulfonation. Also, purified 3,3′-Sulfonated-4,4′-dichlorodiphenyl sulfone (SDCDPS) is gotten by recrystallization procedure of Isopropanol-H2O. Sulfonated Poly(arylene ether sulfone) (SPAES) is synthesiszed from 3,3′-Sulfonated-4,4′-dichlorodiphenyl sulfone (SDCDPS), 4,4′-Dichlorodiphenyl sulfone (DCDPS) and 4,4′ -Biphenol, and is called Aromatic Substituton and Condensation Polymerization. Poly(arylene ether sulfone) copolymer which has a very high viscosity is synthesised through direct polymerization using Potassium carbonate to catalyst. The result of synthesis are confirmed by methods such as FT-IR Spectrum and 1H-NMR Spectrum.
