The synthesized GAP and triblock copolymer were characterized by Fourier-transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), and nuclear magnetic resonance spectroscopy (1H and 13C NMR). The thermal stability of the triblock copolymer PPG-GAP-PPG was studied by differential scanning calorimetry (DSC) and thermogravimetry (TG). The DSC results showed that the glass transition temperature (Tg) of the triblock copolymer (Tg = −63 °C) was lower than that of neat low molecular weight GAP (Tg = −53 °C). Furthermore, the results indicated that this triblock copolymer is more stable than GAP. The influence of heating rate (10, 20, 30 and 40 °C·min−1) illustrated that increasing the heating rate results in an increase in the triblock copolymer’s decomposition temperature. Non-isothermal methods, proposed by ASTM E698, Flynn-Wall-Ozawa (FWO) and Kissinger, were used to calculate the kinetic parameters, such as activation energy and frequenc factor, for the thermal decomposition of the triblock copolymer PPG-GAP-PPG, using the DSC-DTG Central European Journal of Energetic Materials ISSN 1733-7178; e-ISSN 2353-1843 Copyright © 2020 Łukasiewicz Research Network – Institute of Industrial Organic Chemistry, Poland 263 Study on the Thermal Stability and Decomposition Kinetics...

The heat of combustion was determined in a calorimeter and the pressure history was measured in a manometric bomb. Ballistic parameters, such as maximum pressure, propellant force and covolume of gaseous products, as well as the dynamic vivacity, were determined based on the experimental results. The sensitivities to friction and impact were determined for the tested propellants. Calculations of the ballistic characteristics (the heat of combustion, propellant force, covolume and ratio of specific heats of the combustion products, and ballistic energy) were performed. The theoretical parameters were compared with the experimental data and quite good agreement was found between them. The largest differences occurred in the cases of propellant force and covolume. This disagreement is explained. An analysis of the test results and a comparison of the parameters of the RDX-based propellants and the JA2 propellant allowed the possibility of using the tested propellants in ammunition to be assessed.","PeriodicalId":9679,"journal":{"name":"Central European Journal of Energetic Materials","volume":"17 1","pages":"223-238"},"PeriodicalIF":0.8,"publicationDate":"2020-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41821469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The very early stage of evaporation of Bu-NENA from the HTPE/Bu-NENA binder, with a pl/po ratio of 1.2, has been investigated. The results revealed that the pl/po ratio has strong influences on the mechanical properties. When the pl/po ratio was 1.2, the mechanical properties of the HTPE/Bu-NENA binder were satisfactory, the maximum tensile strength and the elongation at break being 2.39 MPa and 93.27%, respectively. The evaporation rate constant of Bu-NENA from HTPE/Bu-NENA binder with a pl/po ratio of 1.2 increased from 0.31·10–5 to 2.32·10–5 s–1 as the temperature was increased from 50 to 90 °C.

Poly(neopentanediol adipate) (NA) was employed as the deterrent to modify the combustion properties because of ist lower migration rate in storage. Scanning electron microscopy (SEM) was used to observe the morphology of the microporous oblate propellants generated by different processing conditions, and the combustion properties were investigated by closed bomb tests. The SEM images indicated that the skin region displayed smaller cell diameters and lower cell density compared with cells in the core region. The closed bomb tests demonstrated that it was feasible to adjust the progressive combustion performance by controlling the skin-core structure and the NA deterred layer.
