Phenolic stabilizers are primary antioxidants that act as hydrogen donors. They react with peroxy radicals to form hydroperoxides and prevent the abstraction of hydrogen from the polymer backbone. They react with peroxy radicals to form hydroperoxides and prevent the abstraction of hydrogen from the polymer backbone.

The two main classes of antioxidants are free-radical scavengers and peroxide scavengers. The free-radical scavengers are sometimes called primary antioxidants or radical chain terminators whereas peroxide scavengers are often called secondary antioxidants or hydroperoxide decomposers.

Primary Antioxidant – hindered phenolic & amine. Primary antioxidants react rapidly and are termed ‘radical scavengers’. The most important are sterically hindered phenolics and secondary aromatic amines. Hindered phenolic are high molecular weight antioxidants in polymer systems.
