Complexes formed between lithium salts and low molecular weight (0.5 kgmol-') poly(ethylene glycol) have been investigated by differential scanning calorimetry, 'Li nuclear magnetic resonance (NMR), and complex impedance measurements. 'Li NMR linewidths and hence ionic mobilities are strongly influe

## 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
The complexation of three kinds of sequence-ordered acid (co)polymers with a base homopolymer was studied. The acid polymers used are poly(methacry1ic acid) 1, alternating (1 : 1) ethylene-methacrylic acid copolymer 2, and periodic (2 : 1) ethylene-methacrylic acid copolymer 3, and the base polymer
The complexation of poly(4-vinylpyridine) (l), poly(2-methyl-5-vinyIpyridine) (2) and poly(2-vinylpyridine) (3) with bromides, perchlorates and tetraphenylborates of alkali metals in organic solvents was investigated by means of electroconductivity, viscometry and nuclear magnetic resonance spectros
## Measurements of 'Li, 'H and 19F nuclear relaxation times and 'Li linewidths are reported for poly(propylene oxide) complexed with lithium salts (LiClO,, LiBF, and LiAsF,). For PPO,LiBF, and PPO.LiClO, the onset of the 'Li motional line narrowing. occurs at aooroximatelv L. The NMR deco;pling m
The structure of lithium sorbate (C6H7Li02) was determined by single-crystal X-ray diffraction. It may be divided into organic and inorganic layers. The ionic part of the structure consists of a two-dimensional network of corner-and edgesharing lithium oxotetrahedra, a structural pattern already kno
