What is it?
Polyvinyl acetate (PVA, PVAc) is a synthetic resin prepared by the polymerization of vinyl acetate. PVA is normally made through the free radical polymerization of vinyl acetate, which is also a polymer. Polyvinyl acetate, (C4H6O2)n, serves as the film-forming ingredient in water-based (latex) paints; it also is used in adhesives and glues, such as Elmer's Glue.
