Abstract Nitrogen-rich polymers with contents of nitrogen between 50 and 60% were synthesized by radical polymerization using 1-(1-vinyl-1H-tetrazol-5-yl) hydrazine and 1- methyl-1-(1-vinyl-1H-tetrazol-5-yl) hydrazine. The monomers were obtained by substitution reactions of hydrazine derivatives and 5-bromo-1-vinyl-1H-tetrazole. Moreover, the poly-1-(1- vinyl-1H-tetrazol-5-yl) hydrazine was converted into the corresponding 5-azidotetrazolyl- ...
