A monomer containing an electron-withdrawing group and an electron-donative group which can be easily controlled in the upper limit of the amount of a sulfonic acid, which impairs the mechanical properties of a copolymer, and can provide a sulfonated polymer that forms a proton-conductive membrane having a high proton conductivity over a wide temperature range, an excellent mechanical strength and an excellent proton conductivity and showing inhibited swelling in hot water and an aqueous solution of methanol, and a copolymer obtained from the monomer. A monomer containing an electron-withdrawing group and an electron-donative group represented by the following general formula (1): wherein Y represents a iodine atom, chlorine atom or bromine atom; X represents an electron-withdrawing group; B represents an electron-donative group; and Z represents an aryl group having a specific structure or a monovalent condensed ring hydrocarbon group such as naphthyl group.
A monomer comprising an electron-withdrawing group and an electron-donative group represented by the following formula (1):
A copolymer comprising a repeating structural unit represented by the general formula (3) in an amount of from 5 to 95 mol % and having a weight average molecular weight of from 10,000 to 1,000,000:
