Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer widely recognized for its versatile properties and applications across multiple industries. With its unique combination of chemical stability, film-forming ability, and environmental friendliness, PVA has become a crucial material in products ranging from adhesives to biodegradable plastics. This document explores the properties, production, applications, and significance of PVA in modern industries. PVA is synthesized through the polymerization of vinyl acetate, followed by the hydrolysis of polyvinyl acetate (PVAc). The extent of hydrolysis determines the properties of the final polymer, such as solubility and crystallinity. Fully hydrolyzed PVA has lower water solubility but higher tensile strength, whereas partially hydrolyzed variants are more soluble and flexible.
