Results

DSC: Neither Tg (glass transition temperature) nor melting point was observed between 22 to 600 °C.

 

DTA: Neither endothermic nor exothermic peak was observed between 20 to 1000 °C in a nitrogen atmosphere. The peak due to oxidative decomposition was observed at 840 °C in an air atmosphere.

 

Conclusion

The test item has no melting point in the temperature range of 22 - 600 °C. Oxidative decomposition of the test item was occurred at 840 °C.

Applicant's summary and conclusion

Conclusions:
No melting point observed in the temperature range 22-600 °C. The substance undergoes oxidative decomposition in an air atmosphere at 840 °C.
