Applicant's summary and conclusion

Conclusions:
As the test item contains (nominally) 20 % methanol, it was considered that the wide endotherm at approximately 35 to 135 °C (308 to 408 K) was due to volatilization of the methanol.
A review of the proposed components of the test item concluded that the test item should not be volatile. Therefore, it could only be concluded that the wide endotherm at approximately 135 to greater than 450 °C was due to degradation of the test item.
As a result of the low rate of enthalpy change during the onset of decomposition, the onset temperature can only be approximated.
Executive summary:

The test item has been determined to decompose from approximately 135 °C (408 K) at 98.3 to 100.5 kPa. As the test item decomposed, no value for boiling temperature could be determined.
