Any other information on results incl. tables
TGA data show there were two thermal events resulting in weight loss associated with sample decomposition. These thermal events occurred at derivative peak values of 202 and 365 0C and correspond to weight losses of 64.8% and 8.1%, respectively. The overall onset of sample weight loss occurred at approx. 200 oC. A residue remained at 600 C accounting for 27.1 % of the material. A TGA thermograph is attached as Figure 1.

Applicant's summary and conclusion
- Conclusions:
- Analysis by TGA indicates the test substance decomposes before boiling. The test material showed weight loss associated with decomposition at temperatures of 202 deg C and 365 deg. C
- Executive summary:
A thermogravimetric analysis performed according to the ASTM E2550 -07 guideline indicates the test substance decomposes before boiling.
The test material was heated under nitrogen up to 600 oC. Examination of the TGA curve shows that weight loss associated with decomposition occurred. The onset of weight loss occurred at approx. 200 oC. There were two main thermal events at derivative peak values of 202 deg. C and 365 deg. C corresponding to weight loss values of 64.8 and 8.1 %, respectively. A residue remained at 600 oC equivalent to 27.1 % of the material.
