Results and discussion

Boiling point

Decomposition:

yes

Decomp. temp.:

> 240 °C

Remarks on result:

other: As the result was unequivocal only one DSC-measurement was performed

Applicant's summary and conclusion

Conclusions:

Based on the thermic stability determined by DSC, the heat chart shows that the test item starts decomposing at approximately 240°C without melting. Therefore the determination of a boiling point is not possible.
