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 384 0C and 432 0C and account for weight losses of 81.8% and 18.0%, respectively.  The overall onset of sample weight loss occurred at approx.   364 0C.  A residue remained at 600 0C accounting for 0.2% 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 losses of 81.8% and 18.0% associated with decomposition at temperatures of 384 and 432 degrees C, repectively.
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 600oC. Examination of the TGA curve shows that weight loss associated with sample decomposition occurred. The onset of weight loss occurred at approx. 364 oC. There were two main thermal events at derivative peak values of  384 and 432 oC corresponding to weight loss values of 81.8 and 18.0%, respectively. A residue remained at  600oC equivalent to 0.2% of the material.
