Polyvinyl alcohol (PVA), also known as Alcool Polyvinylique in French, is a synthetic polymer that has a wide array of applications across industries due to its unique properties. PVA is created by the polymerization of vinyl acetate, followed by hydrolysis (the removal of acetate groups), which results in a water-soluble polymer. This polymer is commonly used in the production of films, adhesives, textiles, and medical products, among other uses. This article provides an in-depth look at the characteristics, production, properties, and applications of Alcool Polyvinylique.
