other: The test item did not vaporise or decompose at -40°C up to 300°C

Differential Scanning Calorimetry for decomposition

Two negligible endothermic peaks were observed between 25°C and 125°C. The first peak is attributed to the glass transition temperature with its peak of resin relaxation (temperature is actually shifted because of the temperature increase, which is different from the real conditions used for Tg measurement). The second peak is not explained (could be an eventual impurity).

Differential Scanning Calorimetry for boiling point

No peak corresponding to an ebullition (boiling) were observed until 300°C. An endothermic peak corresponding to the glass transition with its resin relaxation peak was observed.

Conclusions:
The test item did not decompose or vapourise between -40°C and 300°C.
Executive summary:

The determination of the boiling point temperature range of the test material Maleated rosin esters of glycerol was performed by Differential Scanning Calorimetry and in accordance with OECD Guideline 103. No boiling was observed until the test item reached 300°C. An insignificant endothermic peak corresponding to the glass transition temperature with its relaxation peak was observed. No decomposition was observed until 300°C (2 peaks were observed but considered insignificant). Based on the result of this study it can be concluded that the test item did not vaporise or decompose at -40°C up to 300°C.
