In the temperature range of 160 - 190 °C an endothermic effect was observed. An exothermic effect could be observed in the temperature range of 210 - 310 °C with an energy of approximately -180 J/g.

A second exothermal effect occurred in the temperature range of 470 to >500 °C with a decomposition energy greater -230 J/g. The effect was not finished at the maximum test temperature of 500 °C.

Conclusions:
In the DSC-measurements the test item showed an endothermic effect in the temperature range of 160-190°C. An exothermic effect could be observed in the temperature range of 210-310°C with an energy of approximately -180 J/g. A second exothermal effect occurred in the temperature range of 470 > 500°C with a decomposition energy greater -230 J/g.
SADT: Due to the fact that the exothermic effect started above 200°C it can be stated that the SADT is > 75°C.
According to the results the test item is classified as follows concerning self-reactive properties:
UN Transportation Regulation: The test item does not have to be classified as a self-reactive substance in class 4, division 4.1 since the SADT is > 75°C.
GHS (CLP Regulation EC 1272/2008 Annex 1: 2.8): The test item does not have to be classified as a self-reactive substance since the SADT is > 75°C.

Description of key information

Study according to OECD guideline 113 (adopted 1981): DSC-measurements: endothermic effect in the range of 160-190°C, exothermic effect in the range of 210-310°C with an energy of approximately -180 J/g, exothermal effect in the range of 470 > 500°C with a decomposition energy greater -230 J/g. SADT > 75°C.

Additional information

In the DSC-measurements the test item 2,4 -Bismaleimidotoluene showed an endothermic effect in the temperature range of 160-190°C. An exothermic effect could be observed in the temperature range of 210-310°C with an energy of approximately -180 J/g. A second exothermal effect occurred in the temperature range of 470 > 500°C with a decomposition energy greater -230 J/g. SADT: Due to the fact that the exothermic effect started above 200°C it can be stated that the SADT > 75°C. According to the results the test item is classified as follows concerning self-reactive properties: UN Transportation Regulation: The test item does not have to be classified as a self-reactive substance in class 4, division 4.1 since the SADT is > 75°C. GHS (CLP Regulation EC 1272/2008 Annex 1: 2.8): The test item does not have to be classified as a self-reactive substance since the SADT is > 75°C.

Justification for classification or non-classification

According to the results the test item is classified as follows concerning self-reactive properties: UN Transportation Regulation: The test item does not have to be classified as a self-reactive substance in class 4, division 4.1 since the SADT is > 75°C.

GHS (CLP Regulation EC 1272/2008 Annex 1: 2.8): The test item does not have to be classified as a self-reactive substance since the SADT is > 75°C.
