SULFONATED POLY(ARYLENE ETHER) ALTERNATING COPOLYMER AND SULFONATED POLY(ARYLENE ETHER) ALTERNATING COPOLYMER CONTAINING CROSSLINKABLE MOIETY IN THE END OF THE POLYMER, AND POLYMER ELECTROLYTE MEMBRANE USING THE SULFONATED POLY(ARYLENE ETHER) ALTERNATING COPOLYMER

摘要

PURPOSE: A sulfonated poly(arylene ether) alternating copolymer is provided to ensure excellent high-temperature stability together with excellent mechanical and electrochemical properties and to be prepared in a thin film form. CONSTITUTION: A sulfonated poly(arylene ether) alternating copolymer represented by chemical formula 1 is formed by equation 1. In the equation 1, SAr shows sulfonated aromatic; Ar1 and Ar2 show non-sulfonated aromatic; k is 0.001 - 1.000; s = 1 - k; n is a repeating unit of a polymer and an integer of 10-500; k and s are a molar ratio of a monomer participating in the reaction.
