ABSTRACT:
A new combination of bonding agents when employed in hydroxy-terminated pbutadiene propellant compositions yields greatly improved high temperature aging characteristics and greatly improved low temperature physical properties for the compositions. The combination or bonding agent system consists of MT4 (reaction product of 2.0 moles of tris 1(2 methylaziridinyl)phosphine oxide, 0.7 mole adipic acid, and 0.3 mole tartaric acid); HX752 (bis isophthaloyl 1(2 methyl)aziridine); and BIDE (butyliminodiethanol) in a weight percent range of the propellant composition of 0.10% to 0.20%, 0.10% to 0.20% and 0.02% to 0.05% respectively.
