MEMBRANE SEMI-PERMEABLE ASYMETRIQUE POUR LE TRAITEMENT DES LIQUIDES BIOLOGIQUES.

摘要

Asymmetric semipermeable membrane and processes for the manufacture of this membrane. …This membrane is based on at least one hydrophobic polymer and at least one copolymer based on acrylonitrile, at least one sulphonic monomer optionally in salt form and optionally at least one nonionic and ionisable, olefinically unsaturated monomer. …The membrane according to the invention is employed for the treatment of biological fluids such as plasma or blood, especially by plasmapheresis or with the aid of an artificial kidney by haemodialysis and/or ultrafiltration.
