Polyvinyl acetate Wikipedia

PVAc emulsions such as Elmer's Glue-All contain polyvinyl alcohol as a protective colloid. In alkaline conditions, boron compounds such as boric acid or borax cause the polyvinyl alcohol to cross-link, forming tackifying precipitates or toys, such as Slime and Flubber. A number of microorganisms can degrade polyvinyl acetate. Most commonly, damage is caused by filamentous fungi—however algae

PVAc

Polyvinylacetate (PVAC, PVA) Properties and Applications. Polyvinyl acetate (PVAc, PVA) is an atactic, highly branched, and noncrystalline thermoplastic, prepared by conventional free-radical polymerization. It has good resistance to UV and oxidation, but is rather brittle below its Tg (ca. 305°) and very sticky above it. PVAc emulsions are produced on a very large scale. 1 They are

The monomer can be polymerized while dispersed in water to form a milky-white emulsion. This fluid can be processed directly into latex paints, in which the PVAc forms a strong, flexible, adherent film. It can also be made into a common household adhesive known as white glue or Elmer’s glue. When employed in coatings or adhesives, PVAc is often partially hydrolyzed to a water-soluble polymer

23 C. PVAc emulsions are thermoplastic polymers, as it is well known, which display glass transition temperature (Tg) near room temperature. Their mechan- ical properties change to a great extent by a slight difference of temperature in the region of the Tg. Therefore the practical bond quality must be strongly de- pendent on temperature.
