ABSTRACT:
Polymerizing 3,3-bischloromethyloxetane to yield halomethyl polymer products having hydroxy functionality and a molecular weight between about 500-15,000 followed by reacting such products with metal azide provides poly(azidomethyloxetanes) particularly useful as energetic binders for explosives, gas generators and gun and rocket propellants. Polyhydric initiators are used in the polymerization step.
