“…For instance, MTNBFP has a very high standard molar enthalpy of formation and could be a highly-promising new candidate for primary explosives. 113 The most probable initial dissociation path for MTNBFP is the release of NO 2 according to dynamic dissociation energies, which are 58.5, 172.5 and 239.2 kJ mol −1 .…”

“…To improve the energetic content of fullerene derivatives, more nitro groups can be introduced on the fullerene skeleton. Such a strategy has been recently attempted, where a high-nitrogen-content derivative, C 60 (NO 2 ) 14 (FP, CP-10), was prepared and characterized, 113 using a prolonged treatment of C 60 in benzene with very high concentrations of N 2 O 4 . However, Cp-10 is not so thermally stable and it deflagrates when heated above 170°C in nitrogen or air, releasing a considerable amount of heat.…”

“…, and NO 2 (1628 cm 21 ). Therefore, the 22.97% mass loss observed in TGA curves of PVPNB-g24 # GAP at 248 C could be attributed to the breakdown of the azide group, 32 nitro group, 33 and urethane group. 34 The decomposed products of PVPNB-g24 # GAP at 305 C were mainly of CO 2 (2326 and 2286 cm 21 ) and esters fragments (1791 and 1771 cm 21 ).…”

A series of energetic polymers, poly(vinyl p-nitrobenzal acetal)-g-polyglycidylazides (PVPNB-g-GAPs), are obtained via cross-linking reactions of poly(vinyl p-nitrobenzal acetal) (PVPNB) with four different molecular weights polyglycidylazides (GAPs) using toluene diisocyanate as cross-linking agent. The structures of the energetic polymers are characterized by ultraviolet visible spectra (UV-Vis), attenuated total reflectance-Fourier transform-infrared spectroscopy (ATR-FT-IR), 1 H nuclear magnetic resonance spectrometry ( 1 H NMR), and 13 C nuclear magnetic resonance spectrometry ( 13 C NMR). Differential scanning calorimetry (DSC) is applied to evaluate the glass-transition temperature of the polymers. DSC traces illustrate that PVPNB-g22 # GAP, PVPNB-g23 # GAP, and PVPNB-g24 # GAP have two distinct glass-transition temperatures, whereas PVPNB-g21 # GAP has one. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) are used to evaluate the thermal decomposition behavior of the four polymers and their compatibility with the main energetic components of TNT-based melt-cast explosives, such as cyclotetramethylene tetranitramine (HMX), cyclotrimethylene-trinitramine (RDX), triaminotrinitrobenzene (TATB), and 2,4,6-trinitrotoluene (TNT). The DTA and TGA curves obtained indicate that the polymers have excellent resistance to thermal decomposition up to 200 C. PVPNBg24 # GAP also exhibits good compatibility and could be safely used with TNT, HMX, and TATB but not with RDX.

“…Figure 9(b) showed the infrared spectra of the gaseous products released by PVB-g-4 # GAP at 250 and 362°C. The decomposed products of PVB-g-4 # GAP at 250°C under nitrogen were mainly of N 2 , CO (2146 and 2110 cm −1 ), NH 3 (963 and 923 cm −1 ) and some ethers fragments (1155, 1122, 1099 and 1033 cm −1 ) [7,32]. Therefore, the 25.44 % weight loss observed in TGA curve of PVB-g-4 # GAP at 250.25°C could be attributed to the breakdown of azide group.…”

A series of new energetic polymers of poly(vinyl benzal acetal)-g-polyglycidylazides (PVB-g-GAPs) were prepared by the cross-linking reactions between poly(vinyl benzal acetal) (PVB) and four different molecular weight polyglycidylazides (GAPs), and their structures were characterized by ATR-FTIR, UV-Vis, 1 H NMR and 13 C NMR. The glass-transition temperatures of PVB-g-GAPs were evaluated by DSC method and the thermal stabilities of PVB-g-GAPs were tested by DTA and TGA methods. The results indicated that all PVB-g-GAPs exhibited good resistance to thermal decomposition up to 200°C and the thermal stability order of the four PVB-g-GAPs were PVB-g-2 # GAP (246°C) > PVB-g-3 # GAP (244°C) > PVB-g-4 # GAP (236°C) > PVBg-1 # GAP (231°C). The glass transition temperatures of PVBg-GAPs from DSC method suggested that the synthesized copolymers were thermoplastic elastomer. Moreover, the compatibilities of PVB-g-4 # GAP with the energetic components of TNT-based melt explosives (HMX, RDX, TNT and TATB) were studied by using the non-isothermal DSC method. The results indicated that PVB-g-4 # GAP exhibited good compatibility with TNT, TATB and HMX, and could be safely used in melt cast explosives.
