PURPOSE:To improve the ionic conductivity by compounding a specific rubber, a poly(oxyethylene) glycol, and an alkali metal salt. CONSTITUTION:100pts.wt. mixture comprising 80 to 99wt.% epichlorohydrin homopolymer and/or epichlorohydrin-ethylene oxide copolymer contg. 90mol% or lower ethylene oxide with a weight-average MW of 100,000 to 2,000,000 and 1 to 20wt.% poly(oxyethylene) glycol or lower alkyl ether thereof with a weight average MW of 5,000 or lower [e.g. monomethyl ether of poly (oxyethylene) glycol] is compounded with 0.5 to 20pts.wt. alkali metal salt (e.g. lithium perchlorate), and, if necessary, a polar solvent. |
