Abstract of the Disclosure A method of making porous polymer containing separators adapted for use in electrolytic electrical devices, particularly elec- trolytic capacitors, the separator capable of absorbing and retaining electrolyte and devices utilizing the resultant separators. The method includes the steps of loading a semi-liquid or liquid polymer containing material with at least one compound and at least one modifier material, solidifying the polymer containing material, and removing at least some of the compound to provide a porous polymer containing separator capable of absorbing and retaining electrolyte. When the separators of the present invention are utilized in electrolytic capacitors, especially aluminum electrolytic capacitors, reductions in capacitor volume without significant loss of capacitance are realized and capacitor manufacture is facilitated.
