ABSTRACT:
Internally plasticized elastomeric binders for projectile propellants are cured polyethers containing THF, CYMMO plus BMEMO, BEEMO and/or OMMO mer units. The polyethers are fluid at room temperature and are miscible with nitrate ester plasticizers. Propellant binders prepared from these polyethers are curable, have low T.sub.g 's, good mechanical properties, and I.sub.sp 's comparable to PEG-based binders.
