Thermo-analytical study of glycidyl azide polymer and its effect on different cyclic nitramines

摘要: Abstract In this work, glycidyl azide polymer (GAP) has been prepared and studied. addition, a series of different plastic bonded explosive (PBXs) based on GAP were using five cyclic nitramines, namely. 1,3,5-trinitro-1,3,5-triazinane (RDX) β-1,3,5,7-tetranitro-1,3,5,7-tetrazocane (β-HMX), cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX), RS-e-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (RS-e-CL-20) 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazaisowurtzitane (TEX). The thermal behavior decomposition kinetics have investigated by means the nonisothermal TG DSC techniques obtained isoconversional methods (Kissinger modified Kissinger-Akahira-Sunose (KAS) methods). It was indicated that significant effect activation energy distribution for nitramines it motivates initial autocatalysis RDX CL-20. mean energies reduced comparing with individual their values are 187.7, 191.6, 110.7, 118.5, 283.8, 146.1, 171.6 kJ mol−1 BCHMX/GAP, CL-20/GAP, RDX/GAP, HMX/GAP peak 1, 2, TEX/GAP respectively. admixture changes an inversely proportional linear relationship between mentioned longest lengths N bonds in nitramine molecules into directly one GAP-PBXs due to possibility complex formation studied nitramines. results show BCHMX/GAP good stability reached same level while RDX/GAP considered lowest value all PBXs.
