FTIR spectroscopic study on the Interaction between Ammonium Perchlorate and Bonding Agents

Abstract: The interaction between ammonium perchlorate and bonding agents has been investigated by means of Fourier transform infrared spectroscopy (FTIR). The analysis results endorse that the interfacial bonding force is hydrogen bond for aziridine type compounds and ionic bond for alkylene polyamine derivatives, respectively.

“…This hypothetical interaction mechanism between AP and polymer matrix has been demonstrated in the literature 32. The linear polyurethane here analyzed can lead to the same proposed structure, although this interaction was investigated by means of FTIR spectroscopy between AP and bonding agents, such as aziridine compounds.…”

“…São compostos com funções orgânicas de amidas aziridínicas hidroxiladas ou não, aminas di ou trihidroxiladas, aminas cianohidroxiladas, amidas di hidroxiladas entre outras. Os agentes de ligação atuam sobre os sólidos, perclorato de amônio e alumínio, através de ligações verdadeiras e/ou por ligações secundárias, adsorção ou atração de cargas 21,23 . superfície da partícula para formar uma camada firme e resistente sobre os mesmos, envolvendo-os completamente permitindo que se liguem à matriz polimérica [25][26][27] .…”

“…A adsorção ocorre normalmente devido à presença de grupos polares na molécula do agente de ligação 27 enquanto grupos aziridínicos homopolimerizam sobre os sólidos, devido a abertura do anel 28 . Os agentes de ligação com estrutura de aminas e amidas atuam sobre o perclorato de amônio preferencialmente através de ligações secundárias 21 . Convêm lembrar que o grão de alumínio possui uma superfície irregular o que também facilita a sua interação com a matriz elastomérica 13,29 .…”

“…Up to the present, many aziridine derivatives have been tested and two of them, (5) and (6), have been used very successfully. 7 Compound (5) is a phosphorus aziridine tris[1-(2-methyl)-aziridinyl]phosphine oxide (MAPO) and (6) is an aromatic aziridine isophthalic 2-methyl aziridine (HX-752).…”

“…Phosphoaziridines (3) and (4) have been shown in experimental and clinical studies to be potent antitumor agents as well as radiation sensitizers 4 . Some aziridine derivatives are also known as bonding agents for solid propellants which have a high potential to improve the mechanical properties of the propellant grains composed of the fuelbinder, hydroxyl terminated polybutadiene (HTPB) and the solid fillers, ammonium perchlorate (AP) and aluminium powder 5 . Nema 6 described the main function of the bonding agent as the enhancement of the adhesive force due to either the primary chemical tie of the functional groups to AP or the secondary polar attraction.…”
