Results and discussion
Melting / freezing point
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Remarks on result:
- other: The test item had no melting temperature between -100 °C and 50 °C. A glass transition was found at -76 °C.
Any other information on results incl. tables
Melting temperature: No melting temperature was found between -100 °C and 50 °C, even by addition of aluminum oxide powder as crystallization aid (Test 1 and 2) and annealing at -40 °C (Test 2). A reproducible glass transition was found at -76 °C in the 1st heating (determination A and B).

B |
-75.6 |
Mean value |
-76 |
The estimated accuracy is ± 1 °C.
Observed thermic processes: No other thermic process was found.
In order to survey the thermic behavior of the test item a preliminary TG/DTA-Test (non-GLP) was run up to 600 °C. An endothermic peak starting at about 150 °C with a total weight loss at 250 °C showed the vaporization of the test item.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
