Calorimetry oxidation stability evaluation

Thermoanalytical techniques such as differential scanning calorimetry (DSC) and thermogravi-metric analysis (TGA) have also been widely used to study rubber oxidation [24—27]. The oxidative stability of mbbers and the effectiveness of various antioxidants can be evaluated with DSC based on the heat change (oxidation exotherm) during oxidation, the activation energy of oxidation, the isothermal induction time, the onset temperamre of oxidation, and the oxidation peak temperature.

Differential scanning calorimetry (DSC) and TGA have been used to evaluate the oxidative and thermal stability of polyamide 6,6 [24, 25]. Eriksson and co-workers [24] evaluated thermal stability in an oxidative environment by isothermal and DSC. They found a decrease in the oxidative stability of the polymer as a result of repeated injection moulding. [Pg.112]
