3.2. Influence of the base temperature
The heating curves show three peaks, one exothermic, and two endothermic, see Fig. 2. The exothermic peak is
present when the measurement is started at -100 °C, but it disappears when the measurement is started at higher temperatures. The coldest endothermic peak shifts to higher temperatures and increases in peak height when started
at higher temperatures. The second endothermic peak is at first not influenced by the base temperature. However,
when the coldest endothermic peak comes closer to the second one these two peaks seem to merge together.
The crystallisation peak in the cooling curve is not affected by the base temperatures until this becomes too high.
