Polyvinyl acetate (PVAc) is a synthetic thermoplastic polymer produced by hydrolyzing polyvinyl chloride or directly polymerizing vinyl acetate monomer. It is widely used in adhesives, coatings, and films where its combination of flexibility, adhesion, and water-solubility make it valuable; PVAc is notably chosen over rigid polymers in applications requiring conformability and over other adhesives where non-toxic, water-based formulations are preferred, such as in food contact and child products.
