    • DFT simulation analysis of yellowing mechanism of polypropylene resin during thermal oxygen aging

    • “In the study of thermal oxidative aging yellowing of polypropylene resin, experts analyzed the yellowing structure and the influence of antioxidants, and found that conjugated carbonyl groups were the main cause of yellowing, while semi hindered phenolic antioxidants were more effective in color protection.”
