Abstract

PURPOSE: To obtain the titled hollow fiber useful for hemodialysis, having improved dialysis properties, by treating an acrylonitrile polymer filamentary material coagulated in a coagulation bath with a specific plasticizer,and by drying the fiber to make a specific amount of the plasticizer remain in the fiber.
CONSTITUTION: A 10W30wt% solution of an acrylonitrile polymer consisting of 60% or more acrylonitrile is extruded through an annular slit into a filamentary material to introduce a liquid which will not coagulate the polymer, e.g. γ-butyrolactone, as a core liquid into the interior hollow of the material. The material is then coagulated in an aqueous coagulation bath, treated with a water-soluble and nonvolatile plasticizer, preferably a 10W40% aqueous glycerol, having preferably a boiling point ≥150°C, and then dried to give the objective hollow fiber containing 3% or more the plasticizer.
EFFECT: Improved selective permeability and toughness.
