Abstract
PolyNIMMO (the homopolymer of 3-nitratomethyl-3-methyloxetane) was crosslinked with an isocyanate to produce a polyurethane crosslinked energetic binder for nitramine-based gun propellants. The rheol. and curing properties of urethane-crosslinked polyNIMMO were tested, and the compatibility, miscibility, viscosity, and mech. properties of combinations with various plasticizers was investigated. The glass transition of mixts. of polyNIMMO and plasticizers were detd. at low temps. and the thermal decompn. behavior of the 85:15 (wt.%) RDX-polyNIMMO explosive and explosives contg. RDX with other polymers were calcd.
