Results and discussion

Melting / freezing point
Remarks on result:
not determinable
Remarks:
The product did not show any melting/freezing point With DSC, instead it showed a glass transition.

Any other information on results incl. tables

The product did not show any melting/freezing point with DSC, instead it showed a glass transition. The glass transition was about

205 K when it was measured at a rate of 10 °C per minute.

Applicant's summary and conclusion
