Abstract

A charge mosaic membrane is made of a cationic polymer and an anionic polymer. At least one of the cationic and anionic polymers is in the form of spheres havinq a diameter of 0.01-10 µm. The charge mosaic membrane has been improved inter alia in the ability to selectively separate an electrolyte or non electrolyte and also in mechanical strength, so that it is useful for the separation of an electrolyte or non-electrolyte or for desalination. A process for the production of the charge mosaic membrane is also described. The pro-duction process can provide the charge mosaic membrane at low cost.
