Key result
Remarks on result:
other: 2,2'(ethene-1,2-diyldi-4,1-phenylene)bis(1,3-benzoxazole) ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.
Conclusions:
2,2'-(ethene-1,2-diyldi-4,1-phenylene)bis(1,3-benzoxazole) did not catch fire on being exposed to air at room temperature of 27°Cpressure of 966 hPa. This indicates that 2,2'-(ethene-1,2-diyldi-4,1-phenylene)bis(1,3-benzoxazole) is not auto-flammable.
Executive summary:

2,2'-(ethene-1,2-diyldi-4,1-phenylene)bis(1,3-benzoxazole) did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that 2,2'-(ethene-1,2-diyldi-4,1-phenylene)bis(1,3-benzoxazole) is not auto-flammable.
