ABSTRACT:
Oxazolines useful as bonding agents in solid rocket propellants are disclosed. The oxazoline bonding agents are capable of polymerizing in the presence of ammonium perchlorate. The bonding agents of the present invention are added to the propellant in a range from about 0.1% to about 3% concentration. Importantly, there is no increase in ammonia liberated above baseline propellant values and no increase in end of mix viscosities by using the oxazolines according to the present invention which provides substantial processing savings.
