PCT No. PCT/GB85/00376 Sec. 371 Date Jun. 20, 1986 Sec. 102(e) Date Jun. 20, 1986 PCT Filed Aug. 21, 1985 PCT Pub. No. WO86/01643 PCT Pub. Date Mar. 13, 1986.A polymeric electrolyte comprising a solution of an ionic salt in a polymer X having a bacbone of formula -A-B-, where A is an oligomeric chain and B is a chain extender group, attached to oligomer A, containing one or more linkage atoms Z selected from Si, C and P, wherein the polymer contains oxymethylene units which are present in one or more of the polymer backbone, sidechains or crosslinks, such that where A is an oxyethylene oligomer of formula -CH2CH2-O)n, n is an integer from 3 to 10 and where the oxyethylene oligomer is contained in a sidechain or crosslink attached at B, n is from 2 to 25.
