摘要： Disclosed is a specific polyamide membrane suitable for hemofiltration, comprising a permselective asymmetric membrane of heteroporous structure comprising a polyamide which comprises a plurality of recurring terephthaloyldiamine units. The membrane has an ultrafiltration capacity of from about 1.5.SM.10.sup.-3 to about 15.multidot.10.sup.-3 cm/s.multidot.bar, determined for water at 0.1 bar and 20.degree. C., a thickness of not more than about 100 microns, and a molecular weight exclusion limit of from about 20,000 to about 70,000 Dalton. The membrane is produced in a process which comprises introducing a solution of the polyamide in a water-miscible organic solvent into an aqueous precipitating liquid to obtain a coagulated membrane sheet, which is subsequently washed and dried.
