“…As shown in Figure a–c, there is one prominent exothermic peak ranging from 253 to 261 °C when subjected to a heating rate of 10 °C/min in DSC, ,,, demonstrating that the energetic binder exhibits good thermal stability, similar to that of the random copolymer . The T p values of the copolymers are primarily influenced by the content of EG and THF.…”

In the field of energetic materials (EMs), soft chains are copolymerized with energetic polymers to improve flexibility. However, this often makes it difficult to achieve simultaneous optimization of the energy level and flexibility due to the random sequence. In this study, a simple approach is presented to develop energetic sequencecontrolled polymers (ESCPs), alternate copolymers poly(3,3-bis(azidomethyl)oxetaneglycol) (P(BAMO-alt-EG)) and poly(3,3-bis(azidomethyl)oxetane-tetrahydrofuran) (P(BAMO-alt-THF)), through click reactions. This approach provides the potential to design and control mechanical and thermal properties in propellant binders by introducing various segments and regulating the sequence structure. These polymers display excellent thermal stability and demonstrate that regulated shorter segmental length promoted better flexibility and less residual carbon content without compromising the energy level of the propellant. The obtained kinetic parameters prove that P(BAMO-alt-EG) released higher heat and accelerated the thermolysis process compared to P(BAMO-alt-THF). These results demonstrate the potential of highly alternating ESCPs as a potential energetic propellant binder.

“…As typical difluoroamino monomers, 3‐difluoroaminomethyl‐3‐methyloxetane (DFAMO) and 3,3‐bis (difluoroaminomethyl)oxetane (BDFAO) have been successfully synthesized by Manser et al 39–42 Unfortunately, owing to the great polarity of NF 2 , the flexibility of these polymers was unsatisfactory for practical use. Li et al 8,43–45 synthesized a series of copolymers and studied their pyrolysis progress, physical and chemical properties (BDFAMO‐THF, DFAMO‐THF, DFAMO‐BAMO, DFAMO‐AMMO, and DFAMO‐NIMMO). Compared with BDFAMO‐THF and DFAMO‐THF, BAMO, AMMO, NIMMO (3‐nitratomethyl‐3‐methyloxetane) were of no great benefit to the flexibility of NF 2 polymers.…”

“…Proverbially, the flexibility of energetic polymer is obstructed by bulky and polar energetic groups, bringing about the decline of mechanical properties 1–11 . To eliminate the defect, plasticizers are traditionally blended to interact physically with polymers, thus improving their flexibility, rheology, and processability.…”

In the field of propellant and polymer-bonded explosives (PBX), energetic polymers may bring poor mechanical properties for bulky groups and polarity. To get rid of the defects, plasticizers with low molecular weight can enhance the flexibility and processability of propellants through monotonous mixing. However, the migration of plasticizers over time may severely disrupt the mechanical property of energetic polymers. In contrast to general plasticization, internal plasticization can regulate flexibility from the perspective of molecular structure. In this context, this review focuses on the internal plasticization of energetic polymers from different dimensions. Hopefully, this review can provide some inspiration for designing energetic polymers to optimize the mechanical properties from various dimensions and integrate them for further research.

“…In the case of PBAMO, both its density and heat of formation are higher than the respective values for GAP, but on the other hand, PBAMO exhibits poor mechanical properties (i.e., higher glass transition temperature) [20,26]. To overcome this problem, a lot of copolymers are synthesized (e.g., DFAMO/BAMO copolymer) [27].…”
