Any other information on results incl. tables

The test item was melted at 100 °C. The vapour pressure could not be measured at 110 °C as the pressure continuously increasing due to slow thermal decomposition. After 2 hours at 110 °C the initially clearless melt has turned into yellow. Therefore an established calculation method was used for vapour pressure estimation.
