 Photo-oxidation of polymers

Photo-oxidation of polymers refers to the chemical reactions that occur in polymers due to exposure to light (particularly ultraviolet (UV) light) and oxygen. This process can lead to the degradation of polymer materials, affecting their physical and chemical properties. ### Key Points about Photo-Oxidation of Polymers: 1. **Mechanism**: - Photons provide energy that can excite electrons in polymer chains, leading to the formation of free radicals.
