Melting / freezing pt.:
-72 °C
Remarks on result:
other: glass transition

Any other information on results incl. tables

Study was performed without adjustment of atm. pressure.

No melting point was found between -100°C and vaporization of the test item.

A reproducible glass transition was found at -72°C in the 2nd heating.
