Abstract
Disclosed herein is a process for the production of an alkylene thioether-arylene thioether copolymer, which comprises copolymerizably reacting a compound having at least one alkali thiolate group and obtained by causing an alkali metal sulfide to act on a poly(arylene thioether) in a water-containing polar organic solvent so as to depolymerize the poly(arylene thioether) with a dihalogen-substituted aliphatic compound in a water-containing polar organic solvent.
