Abstrakt: 1.Azo compounds are some of the most effective photostabilizers for polydienes. A correlation was found between the structure and effectiveness of the azo compounds.2.Azo compounds act simultaneously by two mechanisms: as inhibitors, and as absorbers of light. This makes it possible to quantitatively calculate the light-screening effect of azo compounds based on concepts of the diffusion mechanism of synergism between an absorber of UV light and an antioxidant.
