A series of 1,3,5-trisubstituted isocyanurates (substituents: CH2CH2OH, CH2CH=CH2 and CH2CH2COOH) was synthesized according to a modified literature procedure. Experimental investigations included modification of the synthetic proce- dure in terms of the starting materials, solvents, temperature, isolation techniques, as well as purification and identification of the products. All the synthesized isocyanurates were identified by their melting point and FTIR, 1 H NMR and UV spectroscopic data. Fourier transform infrared spectrophotometry was also used to study the interaction be- tween ammonium perchlorate, hydroxyl terminated poly(butadiene), carboxyl termi- nated poly(butadiene), poly(butadiene-co-acrylonitrile), poly(propylene ether), cyclo- trimethylenetrinitramine and the compounds synthesized in this work, which can serve as bonding agents. The results show that tris(2-hydroxyethyl)isocyanurate is a universal bonding agent for the ammonium perchlorate/carboxyl terminated poly(butadiene)/cy- clotrimethylenetrinitramine composite propellant system.
