Chemiluminescence investigation of thermo-oxidative degradation of polyethylenes stabilized with fullerenes

Chemiluminescence investigation of thermo-oxidative degradation of polyethylenes stabilized with fullerenes

The stabilization effect of various carbon materials: [ C60]fullerene, three adducts with levopimaric acid, two sorts of carbon black and nanocarbon on HDPE, LDPE and LLDPE have been studied by chemiluminescence at 180, 190 and 200 °C. Kinetic parameters: oxidation induction time, rate of oxidation...

Beschreibung
Zusammenfassung:The stabilization effect of various carbon materials: [ C60]fullerene, three adducts with levopimaric acid, two sorts of carbon black and nanocarbon on HDPE, LDPE and LLDPE have been studied by chemiluminescence at 180, 190 and 200 °C. Kinetic parameters: oxidation induction time, rate of oxidation and activation energy were determined. On the basis of these results some considerations on oxidation prevention mechanism are revealed.
