Based on molecular dynamics method, the mechanical properties of P(BAMO/AMMO) with five different monomer mole ratios designed at 328 K, 298 K and 233 K, the mechanical properties of P(BAMO/AMMO) with different mass ratios of Bu-NENA or TMETN, and the effect of P(BAMO/AMMO) on the safety properties of HMX were studied. The main results are as follows: at 298 K, the density of five kinds of P(BAMO/AMMO) is 1.135~1.172 g/cm3, and the P(BAMO/AMMO)5 is the largest (the mole ratio of BAMO to AMMO is 3:1). When the mole ratio of BAMO to AMMO is 2:1, the mechanical properties of P(BAMO/AMMO)4 are the best at three temperatures. Compared with TMETN, the compatibility of Bu-NENA with five kinds of P(BAMO/AMMO) is better, however, the effect of plastification of Bu-NENA on P(BAMO/AMMO) is worse than TNETN. Except for P(BAMO/AMMO)4, TMETN can improve the mechanical properties of P(BAMO/AMMO) polymer with more specific mass fraction, and the plasticizing effect is better than Bu-NENA. Five kinds of P(BAMO/AMMO) can improve the safety of HMX, and the best effect of reduce the sensitivity is obtained when the mole ratio of BAMO to AMMO is 3:1. © 2021, Editorial Dept. of JSRT.
