摘要： 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.

摘要： Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is a fused aromatic thiourea, a fused aromatic urea compound, or a combination thereof. The change-enhancing additive may also include a hindered amine light stabilizer compound. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.
