International Classification:

B01D 39/16
D06M 10/02
D04H 3/007

Abstract:

Charged polymeric webs, such as electret webs, include a thermoplastic resin and a charge-enhancing additive. The additives are substituted benzothiazole compounds or substituted benzoxazole compounds. The substituent groups may be hydroxyl, mercapto, or aromatic groups. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.
