The photooxidation behaviour of polyglycerol (PG) has been studied under irradiation at long wavelengths (λ ≥ 300 nm) at 40°C and in the presence of oxygen. Photoproducts have been identified by FTIR analysis coupled to chemical treatments and analysis of the gas phase was performed by mass spectrometry. The oxidation kinetic curves were plotted as a function of irradiation time depending on the O2 pressure. Results of thermooxidation at 100°C of PG samples are also compared to photooxidation results. A mechanism accounting for the main routes of oxidation is proposed. © 2001 Elsevier Science Ltd.
