Partially hydrolyzed polyvinyl alcohol (PVA) is a versatile water-soluble polymer that results from the controlled hydrolysis of polyvinyl acetate. Unlike fully hydrolyzed PVA, which has more than 98% of its acetate groups converted to hydroxyl groups, partially hydrolyzed PVA typically has a hydrolysis degree between 85% and 89%. This variation gives it unique properties, making it suitable for specific applications across industries like textiles, adhesives, construction, paper, and pharmaceuticals. One of the defining features of partially hydrolyzed PVA is its balance between water solubility and film-forming strength. Because it retains a portion of the acetate groups, it dissolves more readily in cold water than fully hydrolyzed PVA, which generally requires hot water.
