Any other information on results incl. tables
One measurement with the capillary method was performed to clarify the results of the DSC measurements. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approximately 5 mm.
Under consideration of the results from the DSC measurements and the capillary method it was concluded that the test item started to melt at 110 °C. lt could not be excluded that the test item melted under decomposition (formation of gas in the capillary measurement and mass loss in the DSC measurement).
Applicant's summary and conclusion
- Conclusions:
- The test item started to melt at 110°C. It could not be excluded that the test item melted under decomposition.
- Executive summary:
The melting point/melting range of the test item were determined by using the differential scanning calorimetry. Two DSC measurements with a heating rate of 10 K/min showed endothermal effects in the temperature ranges of 110 - 160 °C. An additional measurement with the capillary method was performed in order to clarify the melting range.
Under consideration of the results from the DSC measurements and the capillary method it was concluded that the test item started to melt at 110 °C. lt could not be excluded that the test item melted under decomposition (formation of gas in the capillary measurement and mass loss in the DSC measurement).
