Polyvinyl nitrate is a long carbon chain (polymer) with nitrate groups bonded randomly along the chain. PVN is a white, fibrous solid, and is soluble in polar organic solvents such as acetone. PVN can be … See more Polyvinyl nitrate was first synthesized by submersing polyvinyl alcohol (PVA) in a solution of concentrated sulfuric and nitric acids. This causes the PVA to lose a hydrogen atom from its hydroxy group (deprotonation), … See more Combustion Polyvinyl nitrate is a high-energy polymer due to the significant presence of groups, similar to See more • Nitrate ester • Polyvinyl ester • Vinyl polymer See more PVN is a white thermoplastic with a softening point of 40-50°C. The theoretical maximum nitrogen content of PVN is 15.73%. PVN is a polymer that has an atactic configuration, meaning the nitrate groups are randomly distributed along the main chain. Fibrous … See more Because of the nitrate groups of PVN, polyvinyl nitrate is mainly used for its explosive and energetic capabilities. Structurally, PVN is … See more implantation bleeding at 3 weeks pregnant
