Any other information on results incl. tables
Results:
The test item showed a semi crystalline behavior.
A glass transition was found at -100 °C followed by a broad melting
range between about -60 °C and 18 °C with a pronounced peak at 16 °C in the 2nd heating.
Observed thermal processes:
To avoid cold crystallization and to achieve the best possible crystallinity, the test item was annealed at -80 °C. After
this, the test item was still partly crystallized with a glass transition of the amorphous phase at -100 °C (measured with a heating
rate of 2 K/min) and a broad melting range between about -60 °C and +18 °C and a pronounced peak at 16 °C.
In order to survey the thermal behavior of the test item a preliminary TG/DSC-Test (non-GLP) was run up to 600 °C.
An endothermal peak at 298 °C with a total weight lass at 306 °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.
