Applicant's summary and conclusion

Conclusions:
The test substance is regarded as thermically stable.
Executive summary:

For assessment of thermal stability a dynamic differential calorimetry screening method according to DIN 51007 was conducted (BASF SE, SIK-Nr. 12/2240, 2012). Two exothermic reactions were seen. One exothermic reaction was measured with an onset temperature of 250 °C, a peak temperature of 257 °C and a released heat quantity of 60 J/g. The second exothermic reaction was observed at an onset temperature of 325 °C with a peak temperature of 387 °C and a released heat quantity of above 270 J/g. The measurements showed onset temperatures of above 200 °C and released heat quantities of below 500 J/g. The substance is therefore regarded as thermically stable.
