| 摘要 |
The present invention relates to a semipermeable asymmetric hollow fiber membrane based on polyethersulfone or polysulfone and a blend of low and high molecular weight PVP, wherein the membrane has a significantly improved permeability and selectivity (e.g. for myoglobin), to a process for manufacturing such a membrane and to the use of the membrane in, for example, haemodialysis, haemofiltration or haemodiafiltration. Membranes of the above kind present special advantages when they are used in connection with different kinds of medical treatments. They may also be used in dialysis and filtration in general, for example in water purification or dehydration.
