Abstract
ABSTRACT The effect of triethanolamine (TEA) on thermal behavior of glycidyl azide polymer (GAP) has been investigated by direct pyrolysis mass spectrometry technique. It has been observed that thermal degradation of GAP-TEA mixture also begins with the cleavage of the side groups as in the case of GAP. Again, the main decomposition started with the elimination of molecular nitrogen from the azide functional group, and a quite similar degradation mechanism has been proposed. The increase in the thermal stability of GAP in the presence of TEA was attributed to formation of a crosslinked structure. The heating rate had little impact on the relative abundances of the degradation products of the GAP-TEA mixture contrary to what has been observed for GAP. Thus, it may be proposed that the effect of heating rate on thermal degradation behavior of a crosslinked polymer is negligible.
