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.
