ABSTRACT:
A permselective membrane, suitable for use in electrolytic cells, is conditioned for such use by expanding it to a desirable extent by immersing it in or coating it with a liquid solvent system in which the membrane exhibits a substantially flat expansion vs. time curve for at least the first four hours after the completion of such immersion or coating, after which the membrane is mounted so as to be ready for use. When inserted into an electrolytic cell, in contact with the electrolyte thereof, the membrane will then be of such a size as to produce the desired amount of tension thereon, making the membrane flat and non-sagging, without over-contraction which could lead to tearing.
