The purpose of this paper was the expansion of new nitrogen-rich, energetic polymers based on tetrazoles. The requirement to the polymers was the suitability as energetic binders. So, the polymers should relieve high thermal and physical stabilities, in order to stabilize the energetic expletive, along with mild to well eruptive characteristics. These nitrogen-rich polymers, obtained by radical homopolymerization of 4-chloromethylstyrene and radical copolymerization of acrylonitrile and 4-chloromethyl styrene with different ratios followed by replacement of all the chlorine atoms of 4-chloromethyl styrene with cyanide ions and formation of tetrazole rings from cyanide groups in dimethylformamide at elevated temperatures. These polymers, obtained in good yields, were characterized by FT-IR and 1H-NMR spectroscopy; differential scanning calorimeter (DSC) and GPC studies. The advantage of these polymers is that the tetrazole rings are stabilized by the formation of hydrogen bridges of NH-protons. Energy of all nitrogen-rich polymers was calculated by Materials Studio program.
