Abstract: 

The thermooxidative degradation of polytetrafluoroethylene(PTFE), both pure and ‎containing additives such as: carbon(graphite) (C), bronze (BZ) and glass fibre (GF), ‎has been studied by non-isothermal thermo-differential analysis (DTA). The values of ‎kinetic parameters obtained from the DTA data, on the basis of thermo-kinetic ‎equations, were compared with the values obtained from the non-isothermal thermo-‎gravimetric analysis(TG-DTG) and a good agreement was achieved. The analysis of ‎the characteristic temperatures and of the kinetic parameters from DTA-DTG data ‎revealed that the thermal stability and mechanism of thermooxidative degradation ‎depend on the nature and concentration of additives. The results were confirmed by ‎the existence of a real compensation effect. The following equation was derived for ‎the compensation effect: In A=0.1410 E- 0.15‎‏.‏
