Polyvinyl nitrate (PVN) is a polymeric explosive material, an ester of nitric acid and polyvinyl alcohol. It is prepared by nitration of polyvinyl alcohol or transesterification of polyvinyl acetate. It is a thermoplastic substance with softening zone between 30-45 °C, depending on the molecular weight of the starting polyvinyl alcohol.
Polyvinyl nitrate can be used in some moldable propellants and explosives.
