Radically Different Antioxidants: Thermally Generated Carbon-Centered Radicals as Chain-Breaking Antioxidants

摘要

Oxidative processes involving molecular oxygen play a key role in the degradation of many materials.Autoxidation involves a radical chain reaction where each radical initiation can damage numerous molecules in a system.Nature minimizes autoxidation by using chain-breaking antioxidants.Further,significant commercial efforts are invested in chain-breaking antioxidants to prevent degradation of organic materials.
