A process for making suitable for hemodialysis and the membranes thus prepared asymmetric permselective membranes.

摘要

SE has a symmetrical membrane permeability SUITABLE FOR SELECTIVE hemodialysis, hemodiafiltration and hemofiltration blood comprising a first hydrophobic polymer, a second hydrophobic polymer and suitable additives. The membrane is characterized by a three-layer structure comprising a first layer in the FORM OF SKIN FAIRLY FINE, WHICH IS RESPONSIBLE FOR PROPERTIES SieVe, A SECOND LAYER IN THE FORM OF A spongy structure, which has a high permeability and SERVE as support for said first layer and a third layer in the form of a support structure DA membrane stability MECHANICS. ALSO it DESCRIBED FOR A MEMBRANE PROCESS manufacturing.
