Polyvinyl alcohol (PVA) is a synthetic polymer that has gained wide industrial and commercial importance due to its unique combination of physical, chemical, and environmental properties. Unlike many synthetic polymers, PVA is water-soluble, biodegradable under specific conditions, and non-toxic, which makes it especially valuable in applications where safety and sustainability are important. polyvinylalcohol PVA is produced through the hydrolysis of polyvinyl acetate, rather than direct polymerization of vinyl alcohol, which is unstable.
