A process for the production of a poly(arylene thioether) containing phthalic anhydride groups wherein a dihalogen-substituted aromatic compound is reacted with an alkali metal sulfide in a polar organic solvent containing water to produce the poly(arylene thioether) is disclosed. This process comprises causing a monohalogen-substituted phthalic compound to exist in a polymerization reaction system, and controlling a ratio, a/b of the number of moles, a of the charged dihalogen-substituted aromatic compound to the number of moles, b of the charged alkali metal sulfide within a range of 0.8 < a/b < 1.

L'invention décrit un procédé permettant de produire un poly(thioéther d'arylène) contenant des groupes anhydride phtalique, dans lequel on fait réagir un composé aromatique dihalogéné avec le sulfure d'un métal alcalin dans un solvant organique polaire contenant de l'eau. Ce procédé permet de faire réagir dans une réaction de polymérisation un composé phtalique monohalogéné et de régler un rapport molaire a/b de sorte que 0,8 < a/b < 1, où a est le nombre de moles du composé aromatique dihalogéné ajouté et b est le nombre de moles du sulfure d'un métal alcalin ajouté.
