摘要：In a method of producing hollow fiber membranes, wherein a molten polymercharged with a gas under pressure is provided in an extrusion apparatus, the polymermelt including the gas under pressure is extruded from the extrusion apparatus througha hollow fiber-forming extrusion nozzle with a predetermined pressure drop whichprovides for a concurrent expansion of the gas contained in the polymer melt therebyforming a porous hollow fiber membrane.
