Reference
A further DSC run was performed in the temperature range between 25°C and 400°C with the temperature rise adjusted to 10°C/min. The first endothermic reaction (melting point) was followed by a second endothermic reaction starting at about 200°C. After the experiment the test item was black and foamed and had lost about 36% of its mass.
The atmospheric pressure during the measurements was 95.5 kPa.
In order to evaluate the nature of the endothermic heat effect more precisely, a capillary test was performed in the temoerature range from 100°C to 300°C with a heating rate of 20°C/min. Starting at about 150°C, the test item started melting. At about 170°C the test item turned clear and colorless. At about 190°C the test item swelled and foamed at about 220°C it became more viscous and turned yellow. No boiling point could be osserved.
The atmospheric pressure during the measurements was 98.5 kPa.
In conclusion, a boiling could not be determined during the study. The second endothermic heat effect is not due to boiling of the test item. The capillary test showed the decomposition of the test item started (above about 190°C) before boiling could be observed.
