257 Poly-3,3-bis-(azidomethyl)-oxetane
Poly-AMMO is synthesized via cationic polymerisation from the monomer
3-azidomethyl-methyl-oxetane (AMMO). The polymerisation reaction
is quenched with water to get polymer chains with hydroxyl
endgroups which enable to react these pre-polymers later with isocyanate
for curing reaction. Poly-AMMO is suggested as W energetic
binder component in W composite propellants and is in the scope of
actual research.

Poly-BAMO is synthesized via cationic polymerisation from the monomer
3,3-bis(azidomethyl)l-oxetane (BAMO). The polymerisation reaction
is quenched with water to get polymer chains with hydroxyl
endgroups which enable to react these pre-polymers later with isocyanate
for curing reaction. Poly-BAMO has one of the highest nitrogen
content of the W energetic binder components and is suggested
for W composite propellants. It is in the scope of actual research.
