Atmospheric pressure:                                  102.6 kPa

Boil with decomposition, temperature:          Approximately 360°C (633K)

  Discussion

Similar thermographic profiles were obtained using air and nitrogen atmospheres. This indicated that the decomposition was probably thermal and not oxidative.

Conclusions:
The test item has been determined to boil with decomposition from approximately 360 °C (633 K) at 102.6 kPa
Executive summary:

The general physico-chemical properties of 4,4'-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with triethylenetetramine have been determined. 

Boiling Point. Boil with decomposition from approximately360°C (633 K) at102.6 kPa. As the test item decomposed, no value for boiling point could be determined,by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008andMethod 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
