ABSTRACT:
A stoichiometric amount of a polyamine compound selected from the group cisting of cyanoethyl substituted tetraethylene pentamine (TEPAN), or the glycidol reaction product of cyanoethyl substituted tetraethylene pentamine (TEPANOL) is reacted with a stoichiometric amount of perchloric acid to yield an amine salt bonding agent useful in propellant compositions.
This improved method prevents the generation of ammonia (as in prior art method) which has to be removed prior to use of amine salt bonding agent in a propellant composition. Also, a lesser amount of diluent water is involved in this method which offers an advantage by not having to strip an excessive amount of water by heat, purge, or vacuum means.
The amine salt bonding agents prepared by this improved method are shown to be of like identity and quality as shown by IR spectroscopic examination and their testing in a propellant composition.
