Mechanism of the action of light stabilizers of polymers in the photosensitized oxidation of hydrocarbons

Communication 2. Effectiveness of light stabilizers

Conclusions

  1. 1.

    The mechanism of the action of light stabilizers of polymers depends upon their concentration and the wavelength of the exciting light. This dependence was explained quantitatively.

  2. 2.

    For a number of light stabilizers investigated, the quenching and inhibition constants were determined.
