Results and discussion

Melting / freezing point
Decomposition:
yes
Decomp. temp.:
200 °C

Any other information on results incl. tables

No melting temperature was found between -100°C and decomposition

of the test item. In order to survey the thermic behaviour of the test item the determination

was run up to 400°C. Exothermic decomposition was observed above about 200°C.
