Any other information on results incl. tables
Results in detail:
No melting temperature was found between -100 °C and 40 °C, even by addition of aluminum oxide powder as crystallization aid
and annealing at -100 °C and -80 °C (determination Test 2).
A glass transition was found at -108 °C in the 1st heating.
| Determination | glass transition temperature (°C) |
| Test 3 | -107.79 |
| Test 4 | -108.00 |
| mean value | -108 |
The glass transition was measured with a heating rate of 20 K/min according to DIN EN ISO 11357.
Observed thermal processes:
In order to survey the thermal behavior of the test item a TG/DSCTest
(non-GLP) was run up to 810 °C.
An endothermal peak starting at about 80 °C with a weight loss of about 99 % at 200 °C was observed. This is presumably due to the
the vaporization or decomposition of the test item.
