Abstract

Procédé pour empêcher la perte de transparence de mélanges d'esters de polyarylène et nouveaux produits ainsi obtenus. Dans ce procédé, pour empêcher la perte de transparence d'articles conformés préparés à partir d'un mélange d'esters de polyarylène, comprenant un ester de polyarylène et d'autres résines thermoplastiques par le traitement avec de la vapeur d'eau ou de l'eau bouillante, on réduit la teneur en sodium du mélange à moins de 70 ppm. La présente invention est particulièrement utile pour fournir des mélanges perfectionnés d'esters de polyarylène, par un procédé qui permet à des articles préparés à partir de mélanges de ces esters d'être traités à l'eau chaude ou à la vapeur d'eau, sans perte de leur transparence.
