Abstract

PURPOSE:To produce the above-mentioned copolymer membrane useful as the membrane for dialysis of blood (specifically for artificial didney), in which the inhomogeneous membrane structure and large holes do not exist, by dissolving the ethylen-vinyl alcohol copolymer in the specified solvent and by forming the membrane by the wet coagulation under a dilatory condition.
