Abstract
Linear and crosslinked comb-branch polymers have been prepared from the macromonomers CH2 = CH-O-(CH2CH2O)nCH3 where n=3, 5, and 6 7. Comparable ionic conductivity levels could be achieved in both linear and branched system when mixed with several salts, if the crosslink density was kept ~5%. The conductivity-temperature behaviour for the crosslinked systems mixed with LiClO4, LiSO3CF3, LiBF4 and NaClO4 was examined as a function of the length of the oligo (ethylene oxide) side chain. It was found that the maximum conductivities of s=10-4-1.58×10-3 for T=303-373 K were achieved when n=5 for a 5% crosslinked sample mixed with LiClO4 at the composition [Li+] [EO]=0.05. © 1990.
