Abstract
The thermal decomposition of GAP and GAP/B in air and nitrogen were studied by FTIR and TG-DTG. The analysis by FTIR and TG-DTG shows that the azide group elimination reactions of GAP begin at about 170 degrees C and finish around 250 degrees C, and the depolymerization of GAP delays by 40 degrees C; Boron changes the mechanism of thermal decomposition process of GAP, and the results show that GAP/B starts losing mass between 55 and 70 degrees C, which is much earlier than GAP itself does. Furthermore, the depolymerization of GAP almost takes place at the same temperature with the azide group elimination. Some kinetics parameters of the reactions were calculated based on Kissinger's processing methods. The results show that the activation energies of the thermal decomposition of GAP and GAP/B are lower and the reactions are easier to occur under air. The possible reason is that the oxygen containing thermal decomposition of GAP has happened.
