Zusammenfassung:	PURPOSE: To obtain an asymmetric permselective membrane capable of including a specific amount of acid, an acrylnitrile copolymer and a compatibility copolymer by using copolymer composed of each specific composition of acrylonitrile, methallylsulfonic acid or the like and a comonomer formed of group of nonionic vinyl or the like. CONSTITUTION: A copolymer in an acrylonitrile copolymer membrane is composed of a 60-100% acrylonitrile copolymer A to the whole weight and a 40-0% copolymer B in compatibility with the copolymer A. The copolymer A is composed of a 70-95% acrylonitrile A1 as the whole weight base of A component, a 0-1% methallylsulfonic acid or the like, and a comonomer of 5-30% nonionic vinyl or the like. A has 30-50 kg/mol by measuring average molecular weight and has a content of a 2-100 meq/kg strong acid. B is a polymer made of a copolymer with a polyvinylpyrrolidone and a vinylpyrrolidone with an acryl acid ester or a vinyl ether.
