Patent ID: 7846587

Claim:
An ion conductor comprising an ion conducting compound (I) and an electrolytic salt (II), said ion conducting compound being a non-crystalline fluorine-containing polyether compound or a crosslinked product thereof in which said compound has a fluorine-containing group in its side chain and is represented by the formula (1): A-(D)-B (1) wherein D is represented by the formula (2): -(D1) n -(FAE) m -(AE) p -(Y) q (2) where D1 is a an ether unit having a fluoroether group in its side chain and represented by the formula (2a): where Rf is a fluoroether group which may have a crosslinkable functional group; R 1 is a group or bond bonding Rf to a trunk chain; FAE is an ether unit having a fluorine-containing alkyl group in its side chain and represented by the formula (2b): where Rfa is a fluorine-containing alkyl group which may have a crosslinkable functional group; R 1 is a group or bond bonding Rfa to the trunk chain; AE is an ether unit represented by the formula (2c): where R is hydrogen atom, an alkyl group which may have a crosslinkable functional group, an aliphatic cyclic hydrocarbon group which may have a crosslinkable functional group or an aromatic hydrocarbon group which may have a crosslinkable functional group; R 1 is a group or bond bonding R to the trunk chain; Y is a unit having at least one of the formulae (2d-1) to (2d-3): n is an integer of 1 to 200; m is 0 or an integer of 1 to 200; p is 0 or an integer of 1 to 10,000; q is an integer of 1 to 100; the order of bonding of D1, FAE, AE and Y is not specified; A and B are the same or different and each is hydrogen atom, an alkyl group which may have fluorine atom and/or a crosslinkable functional group, a phenyl group which may have fluorine atom and/or a crosslinkable functional group, —COOH group, —OR 2 where R 2 is hydrogen atom or an alkyl group which may have fluorine atom and/or a crosslinkable functional group, an ester group or a carbonate group (when an end of D is oxygen atom, A and B are not a —COOH group, —OR 2 , an ester group and a carbonate group).
