EXAMPLE - Sodium styrenesulfonate (SSNa) (in g) (48), and pentafluorostyrene (PFS) (2.5) were dissolved in dimethylsulfoxide (DMSO) (0.6 L) with heating. Then, azobisisobutyronitrile (AIBN) (0.3) was added dropwise to the dimethylsulfoxide (DMSO) solution. The monomers were polymerized for 24 hours or more. The reaction product was allowed to settle at ambient temperature. Then, a precipitate was colleted from the reaction product and filtered to obtain a poly(styrenesulfonate-pentafluorostyrene) copolymer (P(SSNa-co-PFS)). The obtained copolymer was reacted with ionic exchange resin, to obtain a polystyrenesulfonic acid-pentafluorostyrene copolymer (P(SSA-co-PFS)).
