ABSTRACT OF THE DISCLOSURE Disclosed are macroporous polymeric membranes, suitable above all for the separation of polymers, which consist of the copolymer of a monovinyl monomer, selected from . the group comprising acrylaes, methacrylates, vinylpyridine, N-vinylpyrrolidone, vinyl acetate, and hydroxystyrene, with a divinyl monomer, selected from the group comprising alkylene and hydroxyalkylene diacrylates and dimethacrylates, divinylbenzene, and divinylpyridine, at the ratio of monomers of both types ranging from 5:95 to 95:5 wt.%. The membranes are formed from polymeric globular entities which have the size 0.05 to 0.5 µm and are interconnected by covalent bonds, whereas communicating voids - pores occur between the globuli.
