Applicant's summary and conclusion

Conclusions:
No boiling of the test substance before decomposition has been determined using differential scanning calorimetry (GLP-compliant study in accordance with EC A.2, OECD 103 and EPA OPPTS 830.7220). Decomposition of the substance started at 350°C. The substance has no boiling temperature.
