FIELD: chemistry; physics.
SUBSTANCE: invention relates to the field of physicochemical processes, in particular, to a method for producing dynamic polymeric ultrafiltration membranes. Method of obtaining a dynamic ultrafiltration membrane nylon-polystyrene for the separation of water-oil emulsions, comprising a microporous substrate, onto which a dynamic layer is applied, characterized in that the dynamic layer was obtained by forming a semi-permeable layer on the surface of the porous basement from suspended polystyrene microparticles present in the filtered aqueous solution of acetone with a particle size of 142–452 nm, which are in dynamic equilibrium with a solution that also contains distilled water in a 1:1 ratio, in this case, a polymeric microfiltration membrane of nylon with a pore size of 0.45 mcm was used as a microporous substrate.
EFFECT: technical result is increasing the speed and degree of separation of water emulsions.
