ABSTRACT:
The present invention is a membrane for separating aromatics from feeds which are mixtures of aromatics and saturates and for separating saturated linear hydrocarbons from feeds which are mixtures of saturated linear and saturated branched hydrocarbons. The membrane is a plasma polymer formed from plasma polymerizing monomers. In a preferred embodiment, the membrane is a plasma polymer film formed from plasma polymerizing the monomer 2,4 pentane dione.
