Polymer Additives - Antioxidants
Practically all polymer materials undergo oxidative degradation reactions occurring at one or all of the manufacturing, processing and end-use stages. Antioxidants are highly effective in preventing this degradation to the extent that color development, physical and mechanical property loss is kept within acceptable limits.

Polymer stabilizers
Light stabilizers. Light stabilizer are used to inhibit polymer photo-oxidation, which is the combined result of the action of light and oxygen. Like autoxidation this is a free radical process, hence the antioxidants described above are effective inhibiting agents, however additional classes of additives are also beneficial,...

Antioxidants | Thermal Protection for Plastics | amfine.com
ANTIOXIDANTS. Transition metal ions such as copper and iron can accelerate polymer degradation by catalysis of the oxidation process. Special additives known as metal deactivators are used to chelate with transition metal ions and render them inert as oxidation catalysts.

Natural antioxidants as stabilizers for polymers
Carotenoids are antioxidants at small concentrations, but pro-oxidants when their amount is large. They strongly discolor to the polymer, but fade when they are exposed to light. Flavonoids are the most efficient processing stabilizers, they protect the polymer against thermo-oxidative degradation already at 100 ppm.

Antioxidant
Antioxidant polymer stabilizers are widely used to prevent the degradation of polymers such as rubbers, plastics and adhesives that causes a loss of strength and flexibility in these materials. Polymers containing double bonds in their main chains, such as natural rubber and polybutadiene, are especially susceptible to oxidation and ozonolysis. They can be protected by antiozonants. Solid polymer products start to crack on exposed surfaces as the material degrades and the chains break.
