Journal of chemical theory and computation. This reversible saponification and esterification reaction was a strong hint for hermann staudinger in the formulation of his theory of macromolecules. Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. Polyvinyl acetate water based emulsions is often applied as a liquid that hardens to a solid when the water evaporates.

This is no doubt associated with the fact that the glass transition temperature of 28 c is little above the usual ambient temperatures and in fact in many places at various times the glass temperature may be the lower. Learn more about polyvinyl acetate in this article. Tables 9 and 10 illustrate how the solvency of a mixture for selected polymers can be related to the composition of the mixture. It is also used in adhesives.

Poly vinyl acetate is too soft and shows excessive cold flow for use in moulded plastics. Poly vinyl chloride co vinyl acetate co vinyl alcohol 1 product result match criteria. Polyvinyl acetate is soluble in a number of organic solvents. Sigma aldrich offers a number of poly vinyl acetate products.

In its most important application polyvinyl acetate serves as the film forming ingredient in water based latex paints. Pvac resins produce clear hard films that have good weather resistance and withstand water grease oil and petroleum fuels. The more volatile the solvent the more soluble. Polyvinyl acetate a synthetic resin prepared by the polymerization of vinyl acetate.

Additional properties are high initial tack almost invisible bond line softening at 30 45c good. Predicted solvencies of mixtures of dmso and tetralin or dmso and methyl isobutyl ketone for these eight polymers are tabulated. Solubility of polyvinyl acetate is directly related to the volatility of the solvent. Polyvinyl acetate is also the raw material to make other polymers like.
