Abstract
Dihydropyridazines compounds having antioxidant properties and uses thereof are described herein. These compounds can function as antioxidants that prevent oxidation of materials, including polymers, and as free radical inhibitors to stabilize reactive chemicals, such as monomers against free radical reactions. The dihydropyridazines can be added as small molecule additives or they can be incorporated into molecules bearing dienophilic C═C double bonds through a Carboni Lindsey reaction, which can reduce environmental and health exposure to antioxidants in plastics and allow for a greater quantity of the antioxidants to be used.
