## 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
## Abstract A poly(ethylene oxide)β__block__βpoly(dimethylamino ethyl methacrylate) block copolymer (PEOβ__b__βPDMAEMA) bearing an amino moiety at the PEO chain end was synthesized by a oneβpot sequential oxyanionic polymerization of ethylene oxide (EO) and dimethylamino ethyl methacrylate (DMAEMA)
