Abstract:
1. A fluorine-containing polymer solid electrolyte which has an ionic conductivity of from 10 −10 to 10 1 S/cm measured at 25° C. by alternating current complex impedance method and comprises: (Ib) a non-crystalline fluorine-containing polymer having hydroxyl which has a number average molecular weight of from 500 to 1,000,000, has recurring units having, in its side chain, a structural unit D derived from a fluorine-containing ether and represented by the formula (D): wherein (d1) is —(OCF (d2) is —(OCFX (d3) is —(OCFX (d4) is —(OCH n1, n2, n3 and n4 are the same or different and each is 0 or an integer of 1 or more, n1+n2+n3+n4 is an integer of from 1 to 4; X wherein the structural unit M1b is a structural unit derived from a fluorine-containing ethylenic monomer (m1b) having hydroxyl and represented by the formula (M1b-2): wherein X wherein R the structural unit A is a structural unit derived from a monomer (a) copolymerizable with the monomer (m1b), and the structural units M1b and A are contained in amounts of from 1 to 100% by mole and from 0 to 99% by mole, respectively, and (IIc) at least one selected from ionic polymers and salts thereof.
