Abstract

PURPOSE: A thermoplastic polymer containing a specific amount of inorganic compound is melt spun through nozzles for hollow fiber into hollow fibers, which are annealed, drawn to develop porous structure and further heat set, thus giving novel title hollow fiber being used as membranes for gas separation.
CONSTITUTION: (A) A thermoplastic polymer such as polypropylene including (B) 1W90wt% of inorganic compound such as magnesium oxide is melt spun using nozzles for hollow fiber to form undrawn hollow fibers. After annealed, the hollow fibers are drawn to develop porous structure and further, heat set under constant length or limited relaxation conditions to produce the objective hollow fibers 8. The resulting fibers are fixed to the outer cylinder 6 provided with gas let 1, gas outlet 2, gas-collecting openig 4 with an adhesive 5 to make a module for gas separation, for examle hydrogen from nitrogen.
