Polyvinyl alcohol (PVA) is a synthetic polymer widely used in various industries due to its excellent film-forming, emulsifying, and adhesive properties. It is a water-soluble polymer that is produced by the hydrolysis of polyvinyl acetate (PVAc), where acetate groups are replaced by hydroxyl groups. The degree of hydrolysis determines the solubility and other physical properties of Alcoholes polivinílicos.PVA consists of repeating vinyl alcohol units (-CH₂-CHOH-). However, pure vinyl alcohol is unstable, so PVA is not directly polymerized from vinyl alcohol but instead synthesized from PVAc through hydrolysis. The degree of hydrolysis affects characteristics such as solubility, crystallinity, and thermal stability.
