Abstract

L'invention concerne un procédé de séparation et de purification de polymères d'un produit recyclé (Pr). Le Pr est mis en contact à une température et une pression élevées, avec un solvant d'extraction pour produire un Pr extrait (Pre). Un solvant, dans des conditions suffisantes pour solubiliser le premier polymère, entre en contact avec le Pre pour produire une solution, qui est purifiée à une température et une pression élevées en la mettant en contact avec un milieu solide pour produire une solution purifiée du premier polymère. Le polymère purifié est ensuite séparé de la solution purifiée, et les étapes du procédé sont répétées jusqu'à ce que tous les polymères soient séparés et purifiés.
