Abstract

PURPOSE: To produce an asymmetrical dry semi-permeable membrane by the process in which comprises spreading of a dense solution of a copolymer of PAN or specific AN, the immersion of the spread solution in a non-solvent, the heat treatment of the film thus obtianed at a specified temperature while the size thereof is kept constant in a wet condition and concequently heating of the film thus heat-treated at temperature below the heat-treatment temperature.
