This study explores the aging of polymers under electromagnetic radiation, particularly ultraviolet (UV) radiation. The research aims to understand the theoretical foundations of polymer aging, testing procedures for evaluating aging properties, and methods to enhance UV resistance. The study uses a literature review methodology to examine the impact of UV radiation on polymer decomposition, the testing procedures for determining aging properties, and current technical methods for improving UV resistance. Key findings include the use of additives and UV absorbers to extend the lifespan of polymers by shielding them from UV radiation. Thermal conditions contribute to polymer degradation by breaking down physical and chemical bonds, and thermal oxidative environments accelerate aging due to the presence of UV radiation and high temperatures. The study also discusses the importance of understanding polymer aging in real-world applications, such as agricultural plastics, and the impact of aging on the performance and stability of polymers. The research concludes that while UV radiation can enhance polymer aging, using additives and UV absorbers can mitigate these effects, making polymers more resistant to degradation.This study explores the aging of polymers under electromagnetic radiation, particularly ultraviolet (UV) radiation.
