Title (EN) SEPARATING POLYMER FROM COMPOSITE STRUCTURES
(FR) SÉPARATION DE POLYMÈRE DE STRUCTURES COMPOSITES
Abstract:
(EN) The present invention provides a method of promoting separation of polymer bonded to a substrate of different material, which collectively form at least part of a polymer composite structure, the method comprising: (1) contacting the polymer composite structure with a composition comprising organic solvent which is absorbed within one or both of the polymer and substrate, wherein the composition comprising organic solvent does not dissolve either the polymer or the substrate, and (2) contacting the polymer composite structure provided in step (1) with liquid (i) having a temperature higher than the boiling point of the composition comprising organic solvent used in step (1), and (ii) that does not dissolve either the polymer or the substrate, the action of which promotes separation between the polymer and the substrate.
(FR) La présente invention concerne un procédé facilitant la séparation d'un polymère lié à un substrat de matériau différent, qui forment collectivement au moins une partie d'une structure composite polymère, le procédé consistant à : (1) mettre en contact la structure composite polymère avec une composition comprenant un solvant organique qui est absorbé soit dans le polymère, soit dans le substrat ou dans les deux, la composition comprenant un solvant organique qui ne dissout pas soit le polymère soit le substrat, et (2) mettre en contact la structure composite polymère obtenue à l'étape (1) avec un liquide (i) ayant une température supérieure au point d'ébullition de la composition comprenant un solvant organique utilisé à l'étape (1), et (ii) qui ne dissout pas soit le polymère soit le substrat, dont l'action facilite la séparation entre le polymère et le substrat.
