ABSTRACT:
Dialysis membranes in the form of flat foils, tube foils or hollow fibers of regenerated cellulose are disclosed, with decreased leukopenia effect, in which polymeric acids are chemically bound at least to one membrane surface across bridge-formers chemically bound to the cellulose. Polyacrylic acid, polymethacrylic acid and/or polymaleic acid or also their copolymers with more than 5 Mol % acrylic acid- and/or methacrylic- and/or maleic acid- monomer building blocks come into question as polymeric acids. Celluloses modified with bridge formers are, in particular, amino celluloses, including thereunder also naturally-occurring species such as chitosan.
