Abstract : The patent relates to a curing system for carboxy terminated polybutadiene (PBD) propellant binders consisting of a combination of the ethylaziridine adduct of sebacic acid (BISA) and trimethylaziridinylphosphine oxide (MAPO). The combination of BISA and MAPO is useful in that it forms a curative which results in improved temperature cycling capability and improved aging stability for PBD bound solid propellant grains.
