Abstract
A critical review of the present state of research on the oxidation of cis-1,4-polybutadiene (PB) by singlet oxygen (1O2) and molecular oxygen (3O2) is presented. It is shown that UV irradiation in air without a photo-sensitizer results in a free radical process, β-Carotene is an efficient inhibitor of the oxidation of PB by singlet oxygen. On exposure to UV radiation β-carotene enhances the free radical oxidation of PB.
