Abstract

L‘invention concerne un procédé de séparation de matériaux polymères. Il comprend les étapes suivantes : a) on fournit un support (18) revêtu au moins partiellement d’un polymère thermoplastique (20), ledit polymère thermoplastique présentant une température de transition vitreuse Tg donnée ; b) on abaisse la température dudit polymère thermoplastique (20) à une température Tinf inférieure à ladite température de transition vitreuse Tg dudit polymère thermoplastique ; c) on traite mécaniquement ledit polymère thermoplastique (20) à ladite température Tinf pour détacher ledit polymère thermoplastique dudit support ; et, d) on récupère ledit polymère thermoplastique (20) détaché.
