Abstract

L'invention concerne un procédé de purification d'un polymère récupéré. Le procédé comprend l'obtention d'un polymère récupéré, sa mise en contact avec un premier solvant fluide pour produire un polymère récupéré extrait, puis la dissolution du polymère récupéré extrait dans un solvant pour produire une première solution comprenant un polymère et des contaminants en suspension. La première solution est décantée pour produire une deuxième solution comprenant un polymère et des contaminants restants. La deuxième solution est purifiée par mise en contact de la deuxième solution avec des milieux solides pour produire une troisième solution comprenant un polymère de pureté supérieure. Enfin, le polymère de pureté supérieure est séparé de la troisième solution.
