Remarks:
Two endothermic peaks could be observed (peak maximum: 257°C and 275 °C). The first one could be an indication of melting with parallel decomposition (see mass loss step during thermogravimetric measurement). Upon further heating the DSC-curve showed no more sharp peaks but the typical fluctuating course indicating decomposition. Reweighing after the measurement showed that the sample had lost 93.6 %/ 93.7% of its mass.
