| titleOfInvention | Membrane with porous surface |
| abstract | ABSTRACT "Membrane having a porous surface" A membrane in the form of a flat film, tubular film or hollow filament of synthetic polymers, which has from 10 to 90% by volume, of inter-communicating pores and a smooth surface comprising open pores, the porportion of` openings in the surface amounting to from 10 to 90% is disclosed, a process for the production of such a membrane which comprises a process for the production of a membrane as claimed in claim 1 which comprises extruding a homogeneous mixture of at least two components, one component being a fusible polymer and another component being a liquid inert to the polymer and both components forming a binary system which, in the liquid aggregate state, has a region of complete miscibility and a region with miscibility gaps, at a temperature above the dissociation temperature into a bath which contains the inert liquid of the extruded component mixture and which has a temperature below the dissociation temperature and jardemomg the membrane formed in the form or a flat film, tubular film or hollow filament is also disclosed. |
