Abstract
PURPOSE: To obtain hollow fibers with uniform wall thickness by extruding a spinning solution composed of acrylonitrile, an organic polymer which is soluble in the acrylonitrile, and a polymerization catalyst into an atmosphere of sulfur dioxide or hydrogen sulfide, spinning and polymerizing simultaneously, and removing unreacted substances from the fibers.
