Title
(EN) A PROCESS FOR PRODUCING POLY(ARYLENE SULFIDE)
(FR) PROCEDE DE PRODUCTION DE POLY(ARYLENE SULFURES)
Abstract
(EN)
A novel treatment and recovery process is provided which produces commercially desirable high molecular weight poly(arylene sulfide)s from undesirable low molecular weight poly(arylene sulfide)s. The novel process reduces the quantity of low molecular weight poly(arylene sulfide)s which otherwise have little or no commercial value and can require disposal.
(FR)
L'invention concerne un nouveau procédé de traitement et de récupération permettant d'obtenir des poly(arylène sulfures) à haut poids moléculaire commercialement utilisables à partir de poly(arylène sulfures) à faible poids moléculaire indésirables. Ce nouveau procédé permet de réduire la quantité de poly(arylène sulfures) à faible poids moléculaire qui, sinon, n'auraient que peu ou aucune valeur commerciale, et qui devraient éventuellement être éliminés.
