A DSC-Q200 of TA Instruments was used to measure the specific heat of reaction ([DELTA][H.sub.tot]) of the polymer and the specific heat of decomposition of the DCPO (([DELTA][H.sub.DCPO]).
The heat of decomposition, [DELTA][H.sub.DCPO] ranges between 1,002 J x [g.sup.-1] (5 K x [min.sup.-1]) and 1,091 J x [g.sup.-1] (0.5 K x [min.sup.-1]).
The heat of decomposition obviously increases linearly with x.
This may explain that the values of heat of decomposition obtained in [36, 37, 39-41] differ of about 10 to 30% from the value identified previously with Eq.
The overall heat of decomposition for the HTD and LTD processes of AP containing the complexes 1-3 was 405, 365 and 410 J/g, which was higher than pure AP.
The use of air (oxygen) or nitrogen as a purge gas enables comparison of heat evolved by combustion/oxidation with the heat of decomposition in inert atmosphere.
The exotherm maximum was found at 460 K and the heat of decomposition was of the order of 1000 J [g.sup.-1], i.e.
Molar mass, experimental [T.sub.2] value, heat of decomposition and temperature at the onset of decomposition [T.sub.5] (K).
It is interesting to note that this activation energy value is equal to the heat of decomposition.
