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.

Abstract: A nonwoven fibrous web includes a flame retardant nonwoven fabric coated with a fire retardant, wherein the fire retardant comprises ammonium polyphosphate or alkali metal silicate; and wherein the flame retardant nonwoven fabric has a first major surface and an opposed second major surface; a first nonwoven fabric covering at least a portion of the first major surface; and a second nonwoven fabric covering at least a portion of the second major surface. The first and second nonwoven fabrics each comprise oxidized polyacrylonitrile fibers and optional reinforcing fibers.

Abstract: A class of antioxidant compositions include benzotriazole phenolate salts with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group can be prepared from substituted benzotriazole phenols. The ortho substituent group can be a simple hydrocarbon, alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenolate to another benzotriazole phenolate group.

Abstract: Benzotriazole phenols with substituents either ortho to the phenol hydroxyl group and/or para to the phenol hydroxyl group can be prepared from the unsubstituted benzotriazole phenol by coupling reactions. The ortho substituent group can be a simple alkoxy or amino group, or the ortho substituent group can be a linking group, linking the benzotriazole phenol to another benzotriazole phenol group.
