Any other information on results incl. tables

Thermal Stability (DSC measurement):

The DSC-measurements in closed glass crucibles in a closed high pressure crucibles with the test item showed two endothermic effect in the temperature range of 195 °C - 225 °C and 290 °C -330 °C, respectively.

Melting Point I Melting Range (DSC measurement):

Two measurements in aluminium crucibles with a hole showed an endothermal effect in the temperature range of 180 - 220 °C with an onset temperature of 205.14 °C and 204.89 °C, respectively.

An additional endothermal effect was observed in the temperature range of 270 - 365 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the

endothermal peak with the baseline.
