High molecular mass copolymers (P(EH/EO)s) were synthesized by coordination anionic polymerization of ethylene oxide (EO) and epichlorohydrin (EH), and P(EH/EO)s were used for the preparation of the ion-conducting matrix. The copolymers having EO unit contents of less than 63 mol% were amorphous, an
## Abstract The addition of small amounts of crown ethers was observed to enhance the conductivity of the system PEO~20~LiCF~3~SO~3~ (PEO: poly(ethylene oxide)). Optimum conductivity enhancement was observed for the system PEO~20~LiCF~3~SO~3~(crown ether)~0.003~ when 12βcrownβ4 and benzoβ12βcrownβ4
