SULFONATED POLY(ARYLENE ETHER) HAVING CROSSLINKABLE MOIETY COMBINED IN CHAIN OF POLYMER, SULFONATED POLY(ARYLENE ETHER) HAVING CROSSLINKABLE MOIETIES COMBINED IN POLYMER AND AT POLYMER END GROUP, AND POLYMER ELECTROLYTE MEMBRANE USING SULFONATED POLY(ARYLENE ETHER)

摘要

A sulfonated poly(arylene ether) copolymer having crosslinkable moiety is provided to improve positive ion conductivity and cell performance while maintaining thermal stability, mechanical stability, chemical stability, abd membrane formation ability of conventional polymer electrolyte membrane. A sulfonated poly(arylene ether) copolymer having crosslinkable moiety in the chain of polymer has a structure represented by the chemical formula 1. In the chemical formula 1, SAr1 shows a sulfonated aromatic group; Ar shows a non-sulfonated aromatic group; CM shows a crosslinkable moiety; K is 0.001-1.000; s is 1 - k; b is 0.001-1.000; d is 1 - b; n shows a repeating unit of polymer and is an integer of 10-500.
