3,3-Bis(azidomethyl)oxetane (BAMO) is a oxetane monomer used in energetic propellant binders and plasticizer.^[1]^[2] It is frequently used as a copolymer to improve the physical properties of more commonly used polymers and to give them energetic properties.^[3]^[1]

Preparation edit

BAMO is made by reacting BCMO with sodium azide in an alkaline solution. Tetrabutyl ammonium bromide is used as a phase-transfer catalyst in the reaction.^[1]

PolyBAMO can be made by mixing boron trifluoride diethyl etherate and BAMO in trimethylolpropane. The polymerization of BAMO destroys the oxetane ring, but the azide groups remain intact.^[4]
