“…Kel-F is soluble in acetone, butyl acetate, THF, methyl ethyl ketone, and methyl isobutyl ketone. Hoffman, et al (1989) also monitored the changes in crystallinity of Kel-F and found similar results.…”

“…However, the changes did not affect the performance of the PBX. Subsequent work by Hoffman, et al (1989) on the Kel-F 800 binder determined different methods of annealing and molding to reduce the crystallinity changes. More recent work indicates that PBX-9502 is "aging gracefully" and is a very stable PBX (Skidmore, et al, 1998).…”

“…For semicrystalline polymers, the crystalline structure acts as intermolecular cross-links that increase the modulus between T g and T m . Above T g , the modulus is proportional to the level of crystallinity and small levels of crystallinity can increase the elastic moduli by more than an order of magnitude [25,26]. Above T m , the polymer flows and can be easily processed.…”

“…After the kinetic parameters had been obtained using various kinetic methods, the thermodynamic parameters such as change of enthalpy ΔH # , Gibbs free energy ΔG # , and entropy ΔS # for formation of the activated complex [39] were calculated using the following equations [12][13][14]. These parameters are important indicators of thermal safety.…”

“…Increasing the radiation dose prolongs the effects on the bulk properties of TATB. Some theoretical and experimental studies [11,12] have been undertaken to investigate the effect of radiation on the mechanical and chemical properties of TATB bonded with polymeric binders. TATB may expose with penetrating radiation in the stockpile environment and this may cause the aging signature that is readily manifested with consequences for the lifetime service.…”

1,3,5-triamino-2,4,6-trinitrobenzene (TATB) is a kind of insensitive high explosive that can be used as an energetic material in nuclear weapon and space applications. In this work, we have studied the effect of aging on the properties of TATB from a 20 year old lot that had been in direct contact with casing and natural environment conditions. The kinetics was studied using the temperature at the maximum reaction rate (peak) and isoconversional methods from TGA and DTA data obtained at five heating rates under a nitrogen atmosphere. The properties investigated for thermal stability indicate that there is no change in the properties during prolonged exposure in natural environment conditions. The activation energy calculated by the Kissinger method was 179.9 kJ·mol −1 by DTG and the 176.9 kJ·mol −1 by DTA. The experimental results of kinetic analysis obtained by isoconversional methods are in good agreement and very close to each other. In the analysis of reaction mechanisms, the reaction models could be probably best described by a surface contraction mechanism using the Coats-Redfern and Criado methods. The thermodynamic parameters such as Gibbs free energy, enthalpy and entropy of activation were also investigated. The self-accelerating decomposition temperature (TSADT) and critical temperature for thermal explosion (Tb) were also calculated.
