- other: Pressure not reported
Any other information on results incl. tables
During cooling in Experiment 1, a glass transition was observed between -40 °C and -50 °C. During heating, a glass transition was observed between -50 °C and -25 °C. The inflection point of the glass transition was - 40.54 °C. Experiment 2 was performed as a duplicate of Experiment 1. Similar results as with Experiment 1 were obtained. The inflection point of the glass transition was -40.48 °C. The melting temperature (glass transition) was determined as the average melting temperature obtained from Experiment 1 (-40.54 °C) and Experiment 2 (-40.48 °C).
Applicant's summary and conclusion
- Conclusions:
- A melting point of -41 °C was observed for Procrylat as determined by the OECD 102 method.
- Executive summary:
The melting point of Procrylat was tested using differential scanning calorimetry (DSC). During cooling in both experiments, a glass transition was observed between -40 °C and -50 °C. During heating, a glass transition was observed between -50 °C and -25 °C. The average inflection point of the glass transition was -41 °C. The study was conducted in accordance with the OECD 102 method and was GLP compliant; therefore the study is considered reliable without restrictions.
