Applicant's summary and conclusion

Conclusions:
According to the DSC thermogram, no melting endotherms or crystallization exotherms were observed in the temperature range of the analysis (-90 to 50 °C). One glass transition temperature (Tg) was observed in both the first and second heating scans. The Tg was determined to be -38 °C in the second heating scan using the half height method.
Executive summary:

In an OECD 102 assay, according to the DSC thermogram no melting endotherms or crystallization exotherms were observed in the temperature range of the analysis (-90 to 50 °C). One glass transition temperature (Tg) was observed in both the first and second heating scans. The Tg was determined to be -38 °C in the second heating scan using the half height method.
