Beschreibung
Zusammenfassung:	The present invention relates to a process for the separation of propylene from a gas mixture (GM) comprising propylene and propane by means of a membrane (M) comprising a polyarylene ether sulfone polymer (P) prepared by converting a reaction mixture (RG) comprising at least one aromatic dihalogen sulfone and at least one dihydroxy component comprising trimethylhydroquinone. La présente invention concerne un procédé de séparation de propylène à partir d'un mélange gazeux (GM) comprenant du propylène et du propane au moyen d'une membrane (M) comprenant un polymère de polyarylène éther sulfone (P) préparé par conversion d'un mélange réactionnel (RG) comprenant au moins une dihalogène sulfone aromatique et au moins un composant dihydroxy comprenant de la triméthylhydroquinone.
