ABSTRACT:
A solid polymer electrolyte material made of a copolymer comprising a repeating unit based on a fluoromonomer A which gives a polymer having an alicyclic structure in its main chain by radical polymerization, and a repeating unit based on a fluoromonomer B of the following formula (1):in-line-formulae description="In-line Formulae" end="lead"?CF2═CF(Rf)jSO2X  (1)in-line-formulae description="In-line Formulae" end="tail"?wherein j is 0 or 1, X is a fluorine atom, a chlorine atom or OM {wherein M is a hydrogen atom, an alkali metal atom or a group of NR1R2R3R4(wherein each of R1, R2, R3and R4which may be the same or different, is a hydrogen atom or a monovalent organic group)}, and Rfis a C1-20polyfluoroalkylene group having a straight chain or branched structure which may contain ether oxygen atoms.
