Photo-degradation and photo-stabilisation of the two-phase system poly(vinyl chloride)-polybutadiene

Photo-oxidative degradation of PVC/polybutadiene blends can be decreased by adding metal chelates, such as Cyasorb UV light absorbers 1084 and 2548, to the two-phase system.

THE ROLE OF SINGLET OXYGEN IN THE PHOTOOXIDATION OF POLYMERS

Singlet oxygen oxidation of polymers can cause chain-scission and rapid molecular weight decrease, with various intermediates playing a role in chain-scission.

The photodegradation of polypropylene. IV. UV stabilizer decomposition

UV stabilizers in polypropylene films are more sensitive to irradiation in the presence of air, with peroxy radical attack dominating their destruction.

Effects of metal chelates on the oxidation of polyolefins at high temperatures

Metal chelates can both catalyze and inhibit the oxidation of polyolefins at high temperatures, with NiSDT being the most effective antioxidant at temperatures up to 290°C.

Deactivation of singlet oxygen and triplet pentacene by transition metal complexes

Transition metal complexes effectively deactivate singlet oxygen and triplet pentacene in carbon tetrachloride, potentially enabling efficient photochemical conversion of carbon tetrachloride to carbon dioxide and water.
