Vinyl alcohol can be formed by the pyrolytic elimination of water from ethylene glycol at a temperature of 900 °C and low pressure. WebAug 5, 2024 · Different from alginate, polyvinyl alcohol (PVA) is a synthetic water-soluble polymer with non-ionic, polyhydroxylated, and biocompatible properties, which is often used as a stabilizer during the synthesis process of nanoparticles [Citation 38–42]. Also, PVA is non-toxic and highly biocompatible [Citation 43, Citation 44]. Although PVA ...
