- Conclusions:
- Melting and Boiling Point:
In the differential scanning calorimetry measurements according to Regulation EC No. 440/2008 Methods A.1./A.2. and OECD Test Guidelines 102/103 (1995) endothermic effects were observed in the temperature ranges from 150 °C through 220 °C, from 280 °C through 390 °C and from 390 °C through 500 °C at atmospheric pressure (991 hPa).
The visual observation of the test item heated in a test glass gave that the test item starts to liquefy at 190 °C while bubbles are formed.
Based on the results and observations, it can be assumed that the test item starts liquefying under decomposition with a mass loss of ≥ 84 % at temperatures ≥ 190 °C.
Thermal Stability:
In the differential scanning calorimetry measurements according to OECD Test Guideline 113 (1981), the test item showed two endothermic effects starting at 340 °C and at 410 °C, but no exothermic effects up to 470 °C. At temperatures exceeding 470 °C the DSC signal does not allow the definite interpretation of the thermograms due to a high noise signal.

It is not possible to assign any of the observed endothermic effects definitely to melting or boiling of the test item.
For verification of the DSC results the test item was additionally tested in a test glass. At approx. 190 °C the test item liquefied and small bubbles started to form and to rise in the test glass. The colour of the test item changed to black. The temperature of the test glass was not increased further.
Thermal stability (DSC)
Due to strong noise of the DSC signal, the thermogram of DSC run PN15418 cannot be evaluated properly. In DSC run PN15419 two endothermic effects were observed starting at 340 °C and at 410 °C. Above 470 °C the DSC signal showed a high noise so that the thermograms at this temperatures cannot be interpreted without doubt.
