The emulsion fluid can then instantly be processed as a polyvinyl acetate polymer in products comprising the PVAc as a constituent element. When PVAc is incorporated into emulsion coatings and adhesives, it is normally converted to polyvinyl alcohol first, which is a water-soluble polymer. This is done by means of partial hydrolysis. On a ...

PVA is manufactured by the hydrolysis of polyvinyl acetate in the presence of acids or alkalis. PVA, unlike many polymers, is soluble in water. It dissolves in cold water at a slow rate, but the dissolution is fast at higher temperatures, especially around 90°C. PVA serves as an excellent protective colloid for aqueous emulsions and is employed for this purpose in a host of emulsion and ...

PVA is a vinyl polymer. Polyvinyl acetate is prepared by the polymerization of vinyl acetate monomer (free radical vinyl polymerization of the monomer vinyl acetate). Applications. As an emulsion in water, PVAc 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 ...
