Any other information on results incl. tables

The test substance does not return in its original state after being heated to 150 °C. There are no indications for chemical changes of the test substance in this temperature range (90 -155°C).

It is concluded that the test substance is not stable at temperatures above about 150 °C, in an air as well as in a nitrogen atmosphere.

Reaction or decomposition associated with a considerable loss of mass was observed at temperature above 214°C and a large exothermic heat effect above 265°C.

Applicant's summary and conclusion
