In the DSC-measurements the test item Compimide 183 showed a first exothermic effect in the temperature range of 150 - 300 °C with an averaged energy release of -210 J/g. A second exothermic effect occurred in the temperature range of 400 to >500 °C with an averaged energy release of >-370 J/g.

Conclusions:
In the present study conducted according to OECD guideline 113 (1981) the thermal stability of Compimide 183 was determined using differential scanning calorimetry (DSC) In these measurements the test item showed a first exothermic effect in the temperature range of 150 - 300 °C with an averaged energy release of -210 J/g and a second exothermic effect the range of 400 to >500 °C with an averaged energy release of >-370 J/g.
Therefore the test item is regarded to be stable at room temperature.
