Title: Method and solid propellant with unsaturated aziridine cured binder

Abstract: A new class of multiaziridines are provided having the formula: ##EQU1## WHEREIN R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are monovalent radicals that may be the same or different and are hydrogen, 1-5 carbon alkyl or 1-5 carbon alkenyl, R.sub.5 is a multivalent hydrocarbon radical containing 2 to 24 carbon atoms, and n is an integer from 2 to 4. These multiaziridines are used to produce elastomeric compositions of controlled plasticity and gel content, plus other unique polymeric products, by reaction with polycarboxylic organic compounds, e.g., controlled combination of chain-extending and cross-linking of polycarboxylated polymers.
