The non participation of 1O2 in the photo-oxidation of polybutadiene

Summary

Experiments performed with polybutadiene (PBD) films containing singlet oxygen quenchers, such as: β-carotene, 1,4-diazabicyclo¦2.2.2¦octane (DABCO) and 1,3-diphenylisobenzofuran (DPBF), show that the photo-oxidation of PBD is not initiated by singlet oxygen. On the other hand, the oxidation of a film of PBD pre-irradiated under inert atmosphere strongly suggests that it is a free radical initiated process.

We believe that our results provide strong evidence for the non participation of excited singlet oxygen in the photo-oxidation of commercial polybutadiene.
