N2 - Several polymer binders based on 3,3-bis(azidomethyl)oxetane (BAMO) were studied to explore the compatibility and interaction of the energetic binders with three common energetic oxidants. The compatibilities were studied by differential scanning calorimetry and ratings were obtained according to evaluated standards. The results showed that all the binders based on BAMO had good compatibility with cyclotrimethylenetrinitramine, cyclotetramethylenetetranitroamine and hexanitrohexazaiso-wurtzitane. The work of adhesion (Wa) between binders and explosives was tested via measurement of contact angle and the results are in the following order: chain-extended poly(3,3-bis(azidomethyl)oxetane) (PBAMO) by isophorone diisocyanate (IPDI-CE) with diethyl bis(hydroxymethyl) malonate (IPDI-DBM-CE) > chain-extended PBAMO by IPDI-CE > PBAMO. In addition, similar results were found in the binding energies reported by molecular dynamics, and the average values of Ebinding for the IPDI-DBM-CE system were larger than Ebinding for the other systems due to the formation of hydrogen bonds between –COOEt and –NO2, which improve the bonding abilities.
