The asymmetric polyimide membranes with high solvent-resistance were prepared by the phase inversion process. The membrane (molecular cut-off performance: 35,000) were used to separate the mixture of phospholipids and triglycerides. The two lipids were completely separated with a high flux of n-haxane by using the membranes.
