- Key result
- Remarks on result:
- other: Polymerization of the test substance occured before evaporation and prevented proper determination of the evaporation point
- Conclusions:
- Under the study conditions, degradation of the substance occurred before evaporation and prevented proper determination of the evaporation point ( > 200°C).
- Executive summary:
A study was conducted to determine the boiling point of the substance according to OECD Guideline 103 and EU Method A.2. As the resins are liquid at room temperature, evaporation is measured at supra-ambient temperatures using conventional differential scanning calorimetry (DSC). For temperature-sensitive resins such as acrylate resins, polymerization may occur along with or before evaporation and often prevents proper determination of the evaporation point. A sample of ≈ 10 mg is loaded in a standard aluminum crucible (40 µL) fitted with a pierced lid. The measurements are conducted at a linear heating rate of 10°C/min using commercial DSC equipment (Mettler DSC823e or Q10 from TA Instruments). The DSC cell was flushed with nitrogen gas at a flow rate of 50 mL/min. Unde the study conditions, degradation of the substance occurred before evaporation and prevented proper determination of the evaporation point ( > 200°C) (Leclercq, 2015).
