ABSTRACT:
The present invention relates to a permselective separation membrane that can be used in blood purifying treatment. More particularly, the present invention relates to a polysulfone-based permselective separation membrane which has well-balanced separation properties, highly stable safety and performance, and also can be smoothly assembled into a module, and a method for producing the same.
