Under consideration of the result from the DSC measurement it was concluded that the test item had no melting point and no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.

Executive summary:

The test item had no melting point and no boiling point at atmospheric conditions. Decomposition started at approx. 370 °C.
