By far, the most common source of phenol present in polyolefins is the phenolic antioxidant (AO), typically added to the polymer to ensure good melt processing stability and some degree of long-term thermal stability. The role of phenol based antioxidants is to donate hydrogen atoms to quench free radicals, as well as to generate phenoxy groups
Antioxidant refers to a kind of substance that can delay or inhibit the occurrence of oxidation reaction, ensure the material does not deteriorate during storage, smooth
