Poly(Vinyl Acetate)

Poly(vinyl acetate) (PVAc) is a white to off-white, odorless solid typically supplied as a powder, aqueous dispersion, or resin solution; it softens above 28–40 °C (depending on molecular weight and plasticizer content) and decomposes before melting sharply. It is a synthetic organic polymer formed by free-radical polymerization of vinyl acetate monomer. PVAc serves primarily as a binder and film-forming agent in water-based adhesives, architectural paints, and paper coatings, and is widely used as a precursor for poly(vinyl alcohol) and poly(vinyl acetate-co-ethylene) copolymers. Its main application areas include construction adhesives, interior wall paints, textile sizing, and packaging laminates.

As an emulsion in water, aPVAc emulsions are used as adhesives for porous materials, particularly for wood, paper, and cloth, and as a consolidant for porous building stone, in particular sandstone . Uses : As wood glue PVAc is known as "white glue" and the yellow "carpenter's glue" or PVA glue. As paper adhesive during paper packaging converting In bookbinding and book arts, due to its flexible strong bond and non-acidic nature (unlike many other polymers). The use of PVAC on the Archimedes Palimpsest during the 20th century greatly hindered the task of disbinding the book and preserving and imaging the pages in the early 21st century, in part because the glue was stronger than the parchment it held together.The stiff homopolymer PVAc, but mostly the more soft copolymer a combination of vinyl acetate and ethylene, vinyl acetate ethylene (VAE), is used also in paper coatings, paint and other industrial coatings, as binder in nonwovens in glass fibers. sanitary napkins, filter paper and in textile finishing PVAc can also be used as coating to protect cheese from fungi and humidity. Polyvinyl acetate is also the raw material to make other polymers like : Polyvinyl alcohol -[HOCHCH2]-: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macro molecules. Polyvinyl acetate phthalate (PVAP): Polyvinyl acetate is partially hydrolyzed and then esterified with phthalic acid.
