CA 2096652

A process for preparing poly(arylene sulfide) with reduced metal contamination is produced by contacting a dihaloaromatic compound, a sulfur source, a polar organic compound, and an alkali metal carboxylate in a reaction vessel wherein at least the liquid contacting parts of the vessel are constructed of titanium. In another aspect of the invention a polymer produced by the above described process is provided.

Procédé pour préparer du poly(sulfure d'arylène) dont la contamination par les métaux est réduite par mise en contact d'un composé dihaloaromatique, d'une source de soufre, d'un composé organique polaire et d'un carboxylate de métal alcalin dans un contenant de réaction où au moins les parties du contenant en contact avec le liquide sont en titane. Un autre volet de l'invention concerne un polymère produit par le procédé décrit ci-dessus.
