Beschreibung
Zusammenfassung:	The invention relates to membranes and to a method for the separation of aromatic hydrocarbons from a mixture of various aromatic hydrocarbons or from a mixture of such aromatic hydrocarbons and non-aromatic hydrocarbons. According to the invention the membrane is formed from a polymer whose backbone comprises aromatic centres and one or more of the aromatic centres comprise polar groups. The backbone is preferably an aromatic polyether ketone. The membrane can be modified by radiation, thermal treatment and chemical reaction or a combination of these.
