Abstract : The polyamine compound, TEPAN, a partially cyanoethylated tetraethylene pentamine, is reacted with a selected ammonium salt to form an adduct of TEPAN and the selected ammonium salt. The ammonium salt is selected from ammonium perchlorate (AP), ammonium nitrate (AN), ammonium sulfate (AS), and ammonium formate (AF). The process for preparation of the adduct comprises reacting a water solution of the selected ammonium salt with TEPAN while stirring at room temperature. A TEPAN-glycidol derivative product is also reacted with the selected oxidizer salt to form an adduct of the TEPAN-glycidol derivative product. The disclosed adducts improve mechanical properties and processibility; of composite propellant composition containing about 88 weight percent solids (ammonium perchlorate, aluminum, and Fe2O3 catalyst), a binder of hydroxy-terminated polybutadiene and dioctyladipate cured with a mixture of isophorone diisocyanate and a trifunctional isocyanate.
