Description of key information
m-Xylylenebismaleimide is a solid at 20°C and 1013 hPa as determined visually during testing of physicochemical properties.
In a study according to OECD TG 102, GLP, the test item had an averaged melting point of 120°C. A sharp endothermic peak indicating a melting point could be observed (peak maximum: 126 °C/126 °C; extrapolated onset temperature: 120.68 °C/ 120.27 °C; rounded mean of both determinations: 120 °C).
In a study according to OECD TG 103 differential scanning calorimetry was used in oder to determine the boiling point of m-Xylylenebismaleimide. A boiling point could not be detected because the substance is considered to decompose. The DSC-curve showed two peaks: one exothermic peak (peak maximum: 250 °C/ 251 °C) followed by an endothermic peak (peak maximum: 471 °C). The first one is probably due to exothermic decomposition after melting. The second one may be a result of a partial boiling of the decomposed test item. Due to the fact that the thermogravimetric measurement as well as the DSC-measurement did not show a complete mass loss in that temperature range, no normal boiling point could be observed.
The relative density for m-Xylylenebismaleimide was determined to be 1.38 using the air comparison pycnometer method in a study conducted according to OECD TG 109.
The median particle size was D50 = 22.1 µm as determined in a study conducted according to OECD TG 110. A sample of the test item was brought into a laser beam via a powder dispersing cell. From the diffraction pattern the particle size distribution was calculated.
In a study conducted in accordance with OECD TG 105, GLP, the water solubility of m-Xylylenebismaleimide was determined to be 37.6 mg/L at 20°C and a pH of 5.3.
A surface tension of 60.39 mN/m was measured using the ring method in a test according to OECD TG 115.
The vapour pressure and the partition coefficient were determined by QSAR estimation using the EPISuite Software. The respective values are a vapour pressure of 5.81E-010 Pa at 25°C calculated with the MPBPWIN model (v1.43) and a partition coefficient of 1.60 at 25°C determined with KOWWINv 1.68.
Based on a test conducted according to UN Recommendation on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, Rev. 6 (2015) and UN-Model_Regulations, Rev. 19 (2015), \/Dl 2263 Sheet 1, Grewer-Oven (1990), the test tiem is not considered to be auto flammable, the substance could not be self- ignited. There was also no sign of flammability as determined in a test according to UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids).
In accordance to Regulation (EC) No 1907/2006 (REACH), annex VII explosive properties testing does not need to be conducted as there are no chemical groups associated with explosive properties in the molecule.
In accordance to Regulation (EC) No 1907/2006 (REACH), annex VII, oxidising properties testing does not need to be conducted as there are no chemical groups associated with oxidising properties in the molecule.
