Abstract: The transesterification and polycondensition of hydroxy terminated polyethylene oxide and ethylene glycol with dimethyl terephthalate and sodium dimethyl isophthalate sulfonate lead to the formation of ethylene oxide-(ethylene terephthalate-CO-sodium ethylene isophthalate sulfonate)segmented copolymer(EOTM-SO3Na).This segmented copolymer is a new single cationic conductor.The chain and aggregate structure of EOTM-SO3Na segmented copolymers were characterized by 1HNMR, WAXD and DSCmethods. The ion mobility measured by polar inversion method was approach to 1. The room temperature conductivity of EOTM-SO3Na cationic conductor can get 2.3× 10-6S·cm-1. The temperature dependence of the cationic conductivity for EOTM-SO3Na system can be described by VTF equatlon.

Key words: Ethylene oxide-(ethylene terephthalate-CO-sodium ethylene isophthalate sulfonate) segmented copolymer, Single cationic conductor, Ionic conductivity, Ion mobility
