| [History]
Polyvinyl acetate was discovered in Germany in 1912 by Fritz Klatte. The monomer, vinyl acetate, was first produced on an industrial scale by addition of acetic acid to acetylene with a mercury(I) salt[3] but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene. | [Uses]
As an emulsion in water, aPVAc emulsions 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 "carpenter's glue" or PVA glue. As paper adhesive during paper packaging converting 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. The stiff homopolymer PVAc, but mostly the more soft copolymer a combination of vinyl acetate and ethylene, vinyl acetate ethylene (VAE), is used also in paper coatings, paint and other industrial coatings, as binder in nonwovens in glass fibers. sanitary napkins, filter paper and in textile finishing PVAc can also be used as coating to protect cheese from fungi and humidity. 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 macro molecules. Polyvinyl acetate phthalate (PVAP): Polyvinyl acetate is partially hydrolyzed and then esterified with phthalic acid. | [Uses]

ChEBI: A polymer composed of repeating acetoxyethylene units. | [Preparation]
PVAc is a vinyl polymer. Polyvinyl acetate is prepared by polymerization of vinyl acetate monomer (free radical vinyl polymerization of the monomer vinyl acetate). | [Production Methods]
Polyvinyl acetate is derived from the polymerization of vinyl acetate; the catalysts used in polymerization may include hydrogen peroxide, peroxy sulfates, or various redox combinations. The polymerization process is described as being carried out by charging all ingredients to the reactor, heating to reflux, and stirring until the reaction is complete. Typically, only a part of the monomer and catalyst is initially charged; the remainder is added during the course of the reaction. | [General Description]
Poly(vinyl acetate) [PVAc] is a biocompatible and biodegradable polymer as it has hydrolyzable groups in the side chain,also it is non-toxic and non-carcinogenic.Owing to its biologically friendly nature , it is used in various biomedical application such as artificial organ implant, contact lens,cardiovascular devices and cartilage skin. It is also used in wound dressing and various drug-delivery applications. It has been accepted as reference standard for universal calibration in gel permeation chromatography. | [Industrial uses]
Polyvinyl acetate is a leathery, colorless thermoplasticmaterial that softens at relatively lowtemperatures and that is relatively stable to lightand oxygen. The polymers are clear and noncrystalline.The chief applications of polyvinylacetate are as adhesives and binders for waterbasedor emulsion paints. Vinyl acetate is conveniently prepared bythe reaction of acetylene with acetic acid. | [Solubility in organics]
