Abstract
Polymeric compositions include at least one polymer that is free of ester linkages and an additive that is a benzotriazole phenolate salt with substituents either ortho to the phenol hydroxide group and/or para to the phenol hydroxide group. The substituted benzotriazole phenolate salts 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.
