Poly(vinyl alcohol)

Poly(vinyl alcohol) (PVA) is a white to off-white, odorless, crystalline or amorphous solid, typically supplied as a free-flowing powder or granules; it is non-volatile, water-soluble, and decomposes above 200 °C without a distinct melting point. It is a synthetic, water-soluble polymer classified as a polyol, derived from the hydrolysis of poly(vinyl acetate). PVA serves primarily as a functional polymer in adhesives, textile sizing agents, paper coatings, and as a film-forming binder in packaging and pharmaceutical tablet coatings. It is widely used in applications including emulsion polymerization stabilizers, green composites, water-soluble films for agrochemicals and detergents, and as a precursor for poly(vinyl butyral) and poly(vinyl formal) production.

It is mainly used in the textile industry, as the raw materials of warp pulp, fabric finishing agent, vinylon fiber; interior and exterior wall paint of the building, adhesives; chemical industry use it as a polymerization emulsifier, dispersant and polyvinyl formal, acetal, butyrate aldehyde resin; paper industry use it as a paper binder; agriculture use it as soil improvers, pesticide adhesion synergist and polyvinyl alcohol film; it can also be used for daily cosmetics and high-frequency quenching agent and so on.
Polyvinyl alcohol is a hydrolysis product of polyvinyl acetate, rather than by the polymerization of monomers; the molecular backbone contains
