Copolymers of N-vinylpyrrolidone and 2-methyl-5-vinyltetrazole with various ratios of monomer units were synthesized by radical polymerization using the injection method. The copolymerization parameters for these monomers were calculated by the Kelen―Tudos method (r1 = 14.34; r2 = 0.06) for high degrees of conversion. Copolymers with monomer-unit concentrations up to 70 ± 5 mol% were soluble in water, non-toxic, and effective as radioprotectors.
