Polyvinyl alcohol (PVOH) is a synthetic polymer produced by hydrolyzing polyvinyl acetate, characterized by its hydroxyl groups that provide water solubility and strong intermolecular hydrogen bonding. It is widely used in packaging films, textile sizing, adhesives, and pharmaceutical applications where water solubility, biodegradability, and good mechanical properties are advantageous; engineers select PVOH when they need a thermoplastic that can dissolve in water or degrade in aqueous environments, offering an alternative to petroleum-based plastics in environmentally sensitive applications.
