Antioxidants

Antioxidants. Virtually all polymeric materials undergo oxidation reactions. Oxidation can occur at every stage of the life cycle of a polymer, i.e. during manufacturing and storage of the material or during processing and end-use. Typical manifestations of oxidation of polymers can be change of viscosity during processing, appearance, and loss ...
