Abstract
Procédé et dispositif pour le traitement de polymères du chlorure de vinyle. Le mélange pulvérulent de départ est placé dans un premier mélangeur rapide 1 où l'agitation le porte à 70-160 degrés C, puis il passe dans un ou plusieurs mélangeurs intermédiaires lents 2 chauffés, avant d'être refroidi en 3. La poudre de PCV obtenue, appauvrie en monomères, convient à la fabrication d'emballages de denrées alimentaires.
