SULFONATED POLY(ARYLENE ETHER) COPOLYMER HAVING CROSSLINKING STRUCTURE AT INSIDE POLYMER CHAIN, SULFONATED POLY(ARYLENE ETHER) COPOLYMER HAVING CROSSLINKING STRUCTURE AT INSIDE AND TERMINAL OF POLYMER CHAIN AND POLYMER ELECTROLYTE FILM USING THE SAME

Japanese Patent JP2009091581

A

To provide a sulfonated poly(arylene ether) copolymer having a crosslinking structure at inside a polymer chain, a sulfonated poly(arylene ether) copolymer having a crosslinking structure at inside and a terminal of a polymer chain and a polymer electrolyte film formed by using the same.

A poly(arylene ether) copolymer containing sulfonic acid is synthesized by the polycondensation reaction of a sulfonated dihydroxy monomer (HO-SAr1-OH), a non-sulfonated dihydroxy monomer (HO-Ar-OH), a crosslinkable dihalide monomer (X-CM-X) and a non-sulfonated dihalide monomer (X-Ar-X). The poly(arylene ether) copolymer formed has a crosslinkable structure at inside the polymer chain. Also, the condensation reaction of a crosslinkable monohydroxy monomer or a crosslinkable monohalide monomer allows crosslinking at the terminal of the polymer.
