    Abstract: The present invention relates to permselective asymmetric membranes being suitable e.g. for hemodialysis, hemodiafiltration and hemofiltration of blood, and having improved performance, allowing for enhanced removal of middle molecular weight substances, e.g. inflammatory mediators having a molecular weight between 20 and 40 kDa. The improved sieving characteristics are due to a narrow pore size distribution of the membranes created in the production process. The invention also relates to processes for the preparation of said membranes, devices comprising said membranes, and the use of said membranes in hemodialysis, hemodiafiltration or hemofiltration of blood, as well as in bioprocessing, plasma fractionation and the preparation of protein solutions.
