ABSTRACT:
The invention provides semi-permeable hollow fibres of symmetrical type and of homogeneous microporous structure, with a smooth internal surface, which are obtained by cooling a solution of a copolymer of acrylonitrile and an olefinically unsaturated comonomer carrying optionally salified sulphonic acid groups, in a polar organic solvent with an adjuvant, to give a thermally reversible gel, followed by washing, stretching and relaxation treatments. The new hollow fibres have improved haemocompatibility and are useful in treating blood by haemodialysis, ultrafiltration and/or plasmapheresis.
