UV initiated oxidation and chemiluminescence from aromatic–aliphatic co-polyesters and polylactic acid

The chemiluminescence of UV irradiated aromatic–aliphatic polyesters (Ecoflex and PBAT) and polylactic acid (PLA) was examined in nitrogen and oxygen atmospheres during the non-isothermal temperature runs in the interval from 40 to 250 °C and isothermally from 150 to 190 °C. The non-isothermal therm...

Description
Summary:The chemiluminescence of UV irradiated aromatic–aliphatic polyesters (Ecoflex and PBAT) and polylactic acid (PLA) was examined in nitrogen and oxygen atmospheres during the non-isothermal temperature runs in the interval from 40 to 250 °C and isothermally from 150 to 190 °C. The non-isothermal thermogravimetry and FTIR spectroscopy have been used for the characterization of differences in original samples. The temperature maxima of peroxidic peaks in nitrogen scaling their stability were compared and found to be in the order PBAT
