Compatibility study of BAMO–GAP copolymer with some energetic materials

In order to investigate the safety properties of copolymer of poly(3,3′-bis(azidomethyl)oxetane) and glycidyl azide polymer (BAMO–GAP copolymer) applied in propellants, the compatibilities of BAMO–GAP copolymer with five energetic oxidants, three energetic plasticizers and three fuels, which are the common components used in solid propellants, were studied by DSC method. The rating was obtained according to the evaluated standards of compatibility. The results showed that BAMO–GAP copolymer had a good compatibility with cyclotetramethylenetetranitroamine (HMX), cyclotrimethylenetrinitramine (RDX), hexanitrohexazaisowurtzitane (CL-20), dihydroxylammonium 5,5′-bistetetrazole-1,1′-diolate (HATO), trimethyloleathane trinitrate (TMETN), N-butyl-N-(2-nitroxy-ethyl) nitramine (BuNENA), nitroglycerine (NG), Al and boron (B). However, the binary system of BAMO–GAP and 3,4-dinitrofurzanfuroxan (DNTF) was incompatible. There are interactions between aluminum hydride (AlH3) and BAMO–GAP. It should be more cautious that the BAMO–GAP is used as the binder of propellants containing AlH3.
