Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer widely recognized for its versatility and eco-friendly properties. Its unique combination of characteristics, such as film-forming ability, chemical stability, and biodegradability, has made it indispensable across numerous industries, including packaging, textiles, construction, and healthcare. This article explores the composition, properties, applications, and environmental significance of PVA.Polyvinylalcohol is derived from polyvinyl acetate (PVAc) through a hydrolysis or alcoholysis process that replaces acetate groups with hydroxyl groups.
