“…The kinetics of DOA evaporation from poly(vinly chloride) (i.e. PVC) was studied previously and the activation energies and Arrhenius pre-exponential factors are similar to our measurements for neat-DOA and our more complex mixtures of Hytemp+DOA and PBXN-9 [25].…”

, an HMX-formulation, is thermally damaged and thermally decomposed in order to determine the morphological changes and decomposition kinetics that occur in the material after mild to moderate heating. The material and its constituents were decomposed using standard thermal analysis techniques (DSC and TGA) and the decomposition kinetics are reported using different kinetic models. Pressed parts and prill were thermally damaged, i.e. heated to temperatures that resulted in material changes but did not result in significant decomposition or explosion, and analyzed. In general, the thermally damaged samples showed a significant increase in porosity and decrease in density and a small amount of weight loss. These PBXN-9 samples appear to sustain more thermal damage than similar HMX-Viton A formulations and the most likely reasons are the decomposition/evaporation of a volatile plasticizer and a polymorphic transition of the HMX from  to  phase.

“…It is important to note that with PVC/PMMA blends the reaction ability (volatility) increases with the increase in initial concentration of plasticizers. This result is in agreement with previously reported observations for the evaporation of plasticizers from plasticized PVC .…”

The thermal stability and kinetic parameters for degradation of rigid and plasticized poly(vinyl chloride)/poly (methylmethacrylate) blends have been investigated by using nonisothermal thermogravimetry in a flowing atmosphere of air. For that purpose, blends of variable composition from 0 to 100 wt% were prepared in the presence (15, 30, and 50 wt%) and in the absence of di-(-2-ethyl hexyl) phthalate as plasticizer. Measurements were carried out in the temperature range of 30-550 C and at various heating rates (5, 10, 20, and 40 C/min). The kinetic parameters (E a and A) were determined by applying the integral Kissinger method. Results indicate that these parameters and the thermal stability of the blends are dependent on the blend composition and the amount of plasticizer present. J.

“…The corresponding pre-exponential factor and activation energy E a are reported in Table 2. These values are in good agreement with those previously reported in the literature [1,2] for other types of phthalate plasticizers. Indeed, is well a decreasing function of the molar mass of these volatile compounds.…”

“…Many studies have been focused on the migration of plasticizers from PVC to a liquid media, but rarely from PVC to a gas phase [1][2][3]. Audouin et al [4] have chosen the weight loss as an indicator to quantify the physical loss of the plasticizer.…”

The physical loss of diisodecyl phthalate (DIDP) plasticizer from PVC films of about 50 μm thickness has been investigated between 95 and 160°C in air by FTIR spectrophotometry and gravimetry. Complementary OIT measurements have been performed to follow the stabilizer depletion and to confirm that the dehydrochlorination of PVC remains negligible for all exposure durations under study. As expected for thin PVC films, the overall loss kinetics obeys a first order law, indicating that it is controlled by DIDP evaporation. The corresponding coefficient of DIDP evaporation obeys an Arrhenius law with an activation energy of about 96 kJ mol -1 . These results are in good agreement with those previously reported in the literature for other types of phthalate plasticizers of PVC.
