Molar mass 86.09 g/mol per unit
Density 1.19 g/cm3 (25 °C)
Boiling point 112 °C (234 °F; 385 K)
Properties
The degree of polymerization of polyvinyl acetate is typically 100 to 5000, while its ester groups are sensitive to base hydrolysis and slowly convert Polyvinyl acetate into polyvinyl alcohol and acetic acid.
The glass transition temperature of polyvinyl acetate is between 30 and 45 °C depending on the molecular weight.
Polyvinyl acetate dispersions 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, yeasts, lichens, and bacteria can also degrade polyvinyl acetate.
Discovery
Polyvinyl acetate was discovered in Germany in 1912 by Fritz Klatte.
The monomer, vinyl acetate, was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury(I) salt, but it is now primarily made by palladium-catalyzed oxidative addition of acetic acid to ethylene.
Preparation
Polyvinyl acetate 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 a dispersion in water, Polyvinyl acetatec preparations 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 glue, PVAc is known as "white glue" and the yellow as "carpenter's glue".
As paper adhesive during paper packaging conversion.
In bookbinding and book arts, due to its flexible strong bond and non-acidic nature (unlike many other polymers). The use of PVAc on the Archimedes Palimpsest during the 20th century greatly hindered the task of disbinding the book and preserving and imaging the pages in the early 21st century, in part because the glue was stronger than the parchment it held together.
In handicrafts.
As envelope adhesive.
As wallpaper adhesive.
As a primer for drywall and other substrates
As a gum base in chewing gum
As an adhesive for cigarette paper.
The stiff homopolymer Polyvinyl acetatec, but mostly the more soft copolymer, a combination of vinyl acetate and ethylene, vinyl acetate ethylene (VAE), is also used in paper coatings, paint and other industrial coatings, as a binder in nonwovens in glass fibers, sanitary napkins, filter paper and in textile finishing.
Polyvinyl acetate is also the raw material to make other polymers like:
Polyvinyl alcohol −[HOCHCH2]−:
Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules.
Polyvinyl acetate phthalate (PVAP):
Polyvinyl acetate is partially hydrolyzed and then esterified with phthalic acid.
Applications

Artists' media (since 1945)
Common household water-based white glues
Hot-melt adhesives, sealants, fabric finishing, plastic wood, and inks.
Description
A white, nontoxic thermoplastic resin prepared by the polymerization of vinyl acetate.
Polyvinyl acetate (PVAC) was discovered in 1912 by Dr. Fritz Klatte in Germany.
Polyvinyl acetate is one of the most widely used water-dispersed resins.
Polyvinyl acetate water-based emulsions is often applied as a liquid that hardens to a solid when the water evaporates.
Polyvinyl acetateC resins produce clear, hard films that have good weather resistance and withstand water, grease, oil, and petroleum fuels. Additional properties are high initial tack, almost invisible bond line, softening at 30-45C, good biodegradation resistance, poor resistance to creep under load, and low cost.
Polyvinyl acetate is a thermoplastic polymer commonly used in glues, paint, and a number of industrial adhesives. Polymers are essentially large molecules linked together in such a way that they are very strong and durable. Most plastics and synthetic materials contain them.
Polyvinyl acetate, which is also commonly referred to as “PVA” or “PVAc,” tends to be quite flexible and has a strong binding capability, which is one of the main reasons it’s so popular in products like glue.
Polyvinyl acetate is made from vinyl acetate, and has the chemical formula of (C4H6O2)n.
How It’s Made
Polyvinyl acetate is normally manufactured through the free radical polymerization of vinyl acetate, which is also a polymer. Scientists isolate this compound first, then manipulate it in order to slightly change its structure. Most of the time this happens in water. Monomer molecules of vinyl acetate typically react when they’re submerged in water, and usually create an emulsion that is milky white in color. The emulsion fluid can in most cases be instantly processed as a polyvinyl acetate polymer by removing it from the water and allowing it to stabilize at room temperature.
Physical Properties
Polyvinyl acetate is primarily a synthetic resin polymer. Due its non-polar nature, it tends to be insoluble in water, oils, fats, or gasoline. This makes it very durable. On the other hand, it is soluble in alcohols, ketones, and esters, so this durability isn’t without its limits. Practically speaking, this means that the polymer won’t erode or get weaker when wet, but it probably shouldn’t be exposed to alcohol or related chemicals, at least not for long periods of time.
Polyvinyl acetate has a molar mass of 86.09 grams per mole (g/mol). The ester groups in its structural lattice make it reactive with alkalis, and leads to the formation of polyvinyl alcohol (PVOH, PVA, or PVAL) and acetic acid (CH3COOH). Boron compounds like borax and boric acid also react with the polymer under alkaline settings, leading to the formation of a complex borate-slime-precipitate.
Use in Glues
One of the most common places to find Polyvinyl acetate is in glues.
Polyvinyl acetate was first discovered by a German scientist Dr. Fritz Klatte in 1912 as a binding agent, and ever since that time it has been used in a variety of settings involving porous materials like wood and paper. Many different types of adhesives, from regular craft glues to construction solvents, depend at least in part on this polymer to be as strong as they are.
Polyvinyl acetate is also widely used for the production of general adhesives, which are more commonly known as carpenter's or white glue. A close examination of the ingredient list of most household adhesives will show PVA in some form.
Other Common Uses
Polyvinyl acetate is also used in the paper and textile industry to produce coatings that lend a shiny touch to surfaces.
Polyvinyl acetate is commonly part of the manufacture of latex paints, too. In these settings it helps in form a tough coating and a supportive film.
Polyvinyl acetate is also used as a protective “shell” or casing for cheese to render it safe from humidity and fungi.
Role in Industry
Industrial manufacturers and producers use Polyvinyl acetate, too, but in these cases it’s more commonly found in the form of a liquefied emulsion that can be added to coatings or coverings for machines, or as a lubricant for certain mechanical activities. The polymer typically has a high resistance to UV rays and oxidation, which makes it a good choice for a number of outdoor and high-temperature applications.
Polyvinyl acetate is a polymer with good aging characteristics, but in some cases its water sensitivity can be a problem. This is typically taken care of by formulating it with plasticizers to increase its reliability and stability.
When Polyvinyl acetate 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. The result is stronger and more durable than if the compound had been isolated and used in its raw form.
Polyvinyl acetatec emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties. However, Polyvinyl acetatec emulsions are also widely used in many industrial and consumer end-use applications:
water-based adhesives for woodworking and paper packaging
non-wovens (engineered fabrics)
paper saturations/specialties
paper and paperboard coatings
carpet backings
building and construction products
glass-fiber sizing, chopped strand mat (CSM) and secondary binder technologies

Polyvinyl acetate is a substance produced through the combining of many units of monomeric vinyl acetate (CH3COOCH=CH2). The number of units so combined is typically between 100 and 5,000. This translates to an average molecular weight of between 850 and 40,000.
Polyvinyl acetate may be used as is or modified through chemical reactions to produce other important polymeric substances.
Production
Monomeric vinyl acetate was once prepared by reacting acetylene with anhydrous acetic acid in the presence of a mercurous sulfate catalyst;
Polyvinyl acetate is now produced by a vapor-phase reaction: bubbling ethylene through anhydrous acetic acid in the presence of palladium chloride as a catalyst. An inhibitor is added to avoid spontaneous polymerization.
Polyvinyl acetate may be combined with other chemicals for the purpose of co-polymerization to increase its moisture resistance.
Properties
Polyvinyl acetate is an amorphous polymer, not a crystalline one. The hardest of the polyvinyl esters, polyvinyl acetate offers good adhesion to most surfaces. Unlike some other thermoplastics, it will not turn yellow.
Polyvinyl acetate does not cross-link, thus becoming insoluble, and it can be dissolved in many solvents other than water. One slow-drying formulation combines 5 to 15 percent polyvinyl acetate with ethyl alcohol (ethanol). A fast-drying counterpart combines the same amount of polyvinyl acetate with acetone (dimethyl ketone).
Applications
