The sulfonated poly(arylene ether sulfone)s containing an ethynyl group were synthesized by a direct polymerization of 4,4’-biphenol (BP), the excess of 4,4’-difluorodiphenylsulfone (DFDPS) and 3,3’-disulfonated 4,4’-difluorodiphenylsulfone (SDFDPS), followed by reaction with 3-ethynylphenol (EP). After film casting, the crosslinking reaction by ethynyl end group of copolymers was done by thermal curing process. The properties of the cured films were characterized by various analytic methods, including fuel cell applications. |
