Abstract
Porous separators for electrolytic processes are designed which are characterized by an N.sub.mac t value, where N.sub.mac is the ratio of the resistance (r) of the electrolyte-saturated separator to the resistance (r.sub.o) of an equivalent volume of electrolyte and t is the thickness, in inches, of the separator. The N.sub.mac value is referred to here as the MacMullin Number.
