Key result
Decomposition:
yes
Decomp. temp.:
> 353 - < 416 °C

Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g).

Conclusions:
Decomposition between 353 °C and 416 °C, before melting.
Executive summary:

The test has been conducted according to the internal method SOP-STR 028, corresponding to the OECD 102, using DSC analysis.

Water/imbibition solvent release was observed between 83 °C and 120 °C, followed by a little endothermic event between 188 °C and 294 °C (onset at 205.7 °C, enthalpy: -23.2 J/g) and then decomposition between 353 °C and 416 °C (onset at 356.8 °C, enthalpy: 42.7 J/g).

Description of key information
