Date Nov. 28, 1996Membranes suitable for use in haemodialysis include a separating layer A with a cut-off between 500 and 5,000,000, a support layer B and a layer C which partly determines the hydraulic permeability. The cut-off and hydraulic permeability can be set independently of one another. The membranes are integral, multi-asymmetric, semi-permeable membranes made from epsilon -caprolactam-soluble polymers. The membranes may be in the form of flat, tubular or hollow fiber membranes. |
