METHOD FOR PRODUCING POLYMER COMPOUND

摘要

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): X<1>-Ar<1>-X<2> (1) X<3>-Ar<2>-X<4> (2) -(Ar<1>)q-(Ar<2>)r- (3) [X<1>, X<2>, X<3> and X<4> represent groups separating in the condensation, Ar<1> represents a two-valent aromatic group having at least a sulfonic acid or a sulfonic acid via a connecting group as a substituent, 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.
