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

摘要

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 degreesC. 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. (C) 2003 Elsevier Science Ltd. All rights reserved. [References: 38]
