Although its name implies a homopolymer structure the structure of commercial pva is a copolymer of vinyl alcohol and vinyl acetate as seen in fig. It is soluble in unsaturated polyesters up resins. Polyvinyl acetate pvac was discovered in 1912 by dr. Pva is used as an emulsion adhesive for bag sack and carton making.

Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. No polyvinyl acetate pvac is not soluble in water. Polyvinyl alcohol pva is a synthetic polymer derived from polyvinyl acetate through partial or full hydroxylation. Polyvinyl alcohol pva is a water soluble polymer with a glass transition temperature tg of 80 c.

Pvoh is produced by hydrolysis of pva and the strong hydrogen bonding imparted by the oh groups means that pure pvoh is water soluble. Poly vinyl acetate mowilith structure based name. Emblem in packaging technology 2012. In its most important application polyvinyl acetate serves as the film forming ingredient in water based latex paints.
