摘要
Abstract
The behavior of several antioxidants in poly（methyl methacrylate） （PMMA） was studied using thermo gravimetric analyzer（TG） and the kinetics of thermal degradation was analyzed with Kissinger, Flynn-Wall-Ozawa and Flynn methods. It showed that four kinds of antioxidant 1010, 1076, 702, and BHT increased the initial thermal degradation temperature by 70 ℃ at a content of 0. 5 wt ‰. Further increasing the loading, the change was moderate. The kinetics analysis showed that the antioxidant could only improve the thermal Oxidative stability at the initial period of degradation（the weight loss less than 30 %）, after which the stabilizing effect of antioxidant on PMMA was reduced due to the antioxidant escaped from the system at a higher temperature than the melting point of antioxidant.关键词
