Overall result:

 Discussion

As a result of the initial low rate of enthalpy change during decomposition, the onset temperature could only be approximated.

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 99.6 to 102 kPa.

Executive summary:

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

Boiling Point. Boil with decomposition from approximately360 °C (633K) at 99.6 to 102 kPa by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
