摘要：
The effect of the pre-aging at 250 degrees C before the measurement of thermogravimetry of tetrafluoroethylene-propylene elastomer was studied. The longer the pre-aging time, the more the linearity of the analyzed line with reference to ISO 11358-2 was improved. The activation energy of the sample aged 240 h was from 159 kJ/mol to 164 Id/mol, which was depending on the weight retained. The value obtained with reference to ISO 11358-3 was from 149 kJ/mol to 159 kJ/mol.
