Abstract:

The amorphous polyester 1 a prepared by melt condensation of 1,5-bis-(9-hydroxy-1,4,7-trioxanonyl)naphthalene (2a) and adipoylchloride (3a), which contains bis-1,4,7-trioxanonyl (triethyleneglycol) segments in its main chain, represents a matrix for ion-conducting materials. Despite the fact that only triethyleneglycol segments are present, which are shorter than the minimum required for full solvation of Li+ cations, ion-conductivities of sigma = 3.3 x 10(-5) cm at 368 K are found for Li+/1 a 0.25 (cations per polymer repeat unit). Hence, more than one bis-1,4,7-trioxanonyl segment (either intra-or Interchain) has to be involved in Li+ complexation. The sigma value compares favorably with previous data for more complex polymer matrices.
