Internally-plasticized polyethers from substituted oxetanes

摘要

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 Tg's, good mechanical properties, and Isp's comparable to PEG-based binders.
