Abstract:
A method for producing an acid group-containing polyarylene sulfide of the present invention includes a reaction step of reacting a polyhaloaromatic compound (a), an alkali metal hydrosulfide (b), an alkali metal carboxylate (c), and an aromatic compound (d) having an elimination group and an acid group, which function in a nucleophilic reaction, in the presence of a solid alkali metal sulfide.
