A method for polymerizing a monomer represented by the formula (1) or copolymerizing a monomer represented by the formula (1) and a monomer represented by the formula (2) in the co-presence of a condensation agent comprising a transition metal complex, to thereby produce a polymer compound represented by the formula (3): X1-Ar1-X2(1)X3-Ar2-X4(2)-(Ar1)q-(Ar2)r-(3)[X1,X2,X3 and X4 represent groups separating in the condensation, Ar1 represents a two-valent aromatic group having at least a sulfonic acid or a sulfonic acid via a connecting group as a substitutent, q represents a positive number, r represents 0 or a positive number, and the sum of q and r is 300 or more], characterized in that the above condensation agent and the above monomer are mixed at a temperature of 45°C or higher. The above method allows the production of a polymer compound which exhibits excellent fuel cell characteristics and has a high molecular weight.
