Abstract

PURPOSE: To produce a porous hollow fiber membrane preferably usable as a gas exchange membrane for an artificial lung preventing a leak of serum even after use for a long time and a gas separation membrane for oxygen enrichment.
CONSTITUTION: A double-layered structure composed of thermoplastic resins of the same kind different from each other in mol.wt. is used to undrawn hollow fibers, and these fibers are drawn to produce a porous hollow fiber membrane having a double-layered structure composed of porous and dense layers.
