Abstract

The invention relates to the providing of hydrophobic and hydrophilic polymer-based hollow fiber membranes containing a water-insoluble antioxidant; in particular, the invention relates to the providing of hollow fiber membranes for the extracorporeal treatment of blood, wherein the hollow fiber membranes have improved biocompatibility relative to treatment blood, in particular improved complement activation and lower platelet loss vis-à-vis treatment blood. At the same time, the elution of hydrophilic polymers from the lumen of the hollow fiber membrane is reduced.
