Abstract:
A production process of a poly(arylene sulfide), including (a) a polymerization step of polymerizing at least one sulfur source selected from the group consisting of alkali metal sulfides and alkali metal hydrosulfides and a dihalo-aromatic compound in an organic amide solvent to form a polymer; (b) a separation step of separating the polymer from a liquid reaction mixture containing the polymer formed after the polymerization step; (c) a washing step of washing the polymer with at least one washing liquid selected from the group consisting of water, an organic solvent and a mixed solution of water and an organic solvent as desired; and (d) an aqueous oxidizing solution treatment step of treating the polymer by bringing the polymer into contact with an aqueous oxidizing solution.
