Poly Vinyl Acetate Solubility

Poly vinyl acetate mowilith structure based name.

Poly vinyl acetate solubility.

It is one of the most widely used water dispersed resins. 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. Polyvinyl acetate pva and polyvinyl alcohol pvoh are further examples of ethylene copolymers. Polyvinyl acetate is also the raw material to make other polymers like.

This reversible saponification and esterification reaction was a strong hint for hermann staudinger in the formulation of his theory of macromolecules. Pvoh is produced by hydrolysis of pva and the strong hydrogen bonding imparted by the oh groups means that pure pvoh is water soluble. Polyvinyl alcohol pva is a water soluble polymer with a glass transition temperature tg of 80 c. Polyvinyl alcohol pva is a synthetic polymer derived from polyvinyl acetate through partial or full hydroxylation.

In its most important application polyvinyl acetate serves as the film forming ingredient in water based latex paints. Polyvinyl acetate pvac is an organic chemical and made from polymerization from monomers. Poly 1 acetoxyethylene poly ethenyl ethanoate poly 1 acetyloxiethene. Polyvinyl acetate pvac was discovered in 1912 by dr.

Pvoh is produced by hydrolysis of pva and the strong hydrogen bonding imparted by the oh groups means that pure pvoh is water soluble. Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. Pva is used as an emulsion adhesive for bag sack and carton making.
