Hydrophilic functional copolymers of 1-vinyl-1,2,4-triazole with vinylsulfonic acid sodium salt

The free-radical copolymerization of 1-vinyl-1,2,4-triazole with vinylsulfonic acid sodium salt was conducted. New thermally stable functional water-soluble copolymers of various composition were synthesized. The structure and properties of the obtained copolymers were confirmed by IR, 1 H NMR spectroscopy, and thermogravimetric methods. It was found that 1-vinyl-1,2,4-triazole has higher reactivity than sodium vinylsulfonate. TGA and DSC show that the produced copolymers are stable when heated to 260 °C.
