Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according to a modified literature procedure.     
All the synthesized isocyanurates were identified by their melting point and FTIR, ¹H NMR and UV spectroscopic data. The Fourier transform infrared spectrophotometry was also used to study the interaction between ammonium perchlorate, hydroxyl terminated poly(butadiene), carboxyl terminated poly(butadiene), cyclotetramethylenete-tranitramine, tris[1-(2-methyl)aziridinyl]phosphine oxide and the compounds synthesized in this work. The results show that 1,3,5-tri(2-hydroxyethyl)isocyanurate is a universal bonding agent for the ammonium perchlorate/carboxyl terminated poly(butadiene)/cyclotetramethylenetetranitramine composite propellant system.

Key words: composite propellant, rocket composite propellant, binder, isocyanurates.
