Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer widely used in various industries for its exceptional properties. Although relatively unknown to the general public, it plays a fundamental role in many consumer products and industrial processes. This article explores the characteristics, applications, and ecological implications of PVA.PVA is produced by the polymerization of vinyl acetate monomer, followed by hydrolysis to replace the acetate groups with hydroxyl groups. This process results in a polymer with unique properties, including excellent water solubility and good chemical compatibility.
