Abstract

In a method of making solvent and acid resistant membrane on the basis of polyacrylnitrile (PAN) and a comonomer copolymerized therewith wherein the membrane is formed from a solution by phase inversion, glycidylmethacrylate is used as the comonomer and the membrane formed thereby is then subjected to ammonia.
