Abstract

On décirt un procédé continu de production de polystyrène résistant au choc, selon lequel on enlève hors du courant de recyclage des types spécifiques d'impuretés qui inhibent la polymérisation avant d'envoyer ce courant dans une zone de polymérisation du styrène. Le procédé comprend également un système de contrôle de l'acidité du courant de recyclage.
