ABSTRACT OF THE DISCLOSURE Normally hydrophobic, polyethylene hollow fibers having contiguous microporosity are prepared by extruding a melt of a polyethylene and an ester from a hollow fiber spinnerette, simultaneously cooling and drawing the forming fibers to a ratio of up to 40 to 1, drawing the gelled fibers to an overall ratio of from about 1.5/1 to 800/1 and then removing the ester. The maximum pore radius ranges up to about 50.ANG., and the fibers have gas permeabilities approaching 10-2 cc (STP) per cm2 per second per cm. Hg. transmembrane pressure differential. A significant increase in permeability over polyethylene hollow fibers made according to the teachings of the prior art is achieved.
