Polyvinyl Alcohol (PVOH) is a synthetic, water-soluble polymer known for its excellent film-forming, emulsifying, and adhesive properties. Widely used in industrial and consumer applications, PVOH is valued for its biodegradability, non-toxicity, and high chemical resistance. It is one of the few synthetic polymers that is both water-soluble and environmentally friendly, making it increasingly important in industries seeking sustainable materials.PVOH is produced through the hydrolysis of polyvinyl acetate (PVAc), during which the acetate groups are replaced by hydroxyl groups. The result is a polymer made up of vinyl alcohol repeating units, although in practice, vinyl alcohol itself cannot be polymerized directly due to its instability.
