Poly Vinyl Acetate Monomer

Polyvinyl acetate is synthesized by the emulsion polymerization of vinyl acetate monomer vam.

Poly vinyl acetate monomer.

Learn more about polyvinyl acetate in this article. Vinyl acetate is the acetate ester of vinyl alcohol. In this test the vinyl acetate is extracted from pvac into an appropriate solvent and analysed using gas chromatography with a flame ionization detector. Raw material for many polyvinyl resins.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. 3 the monomer vinyl acetate was first produced on an industrial scale by the addition of acetic acid to acetylene with a mercury i salt 4 but it is now primarily made by palladium catalyzed oxidative addition of acetic acid to ethylene. Celanese is a global leader in polyvinyl acetate homopolymer emulsions often called pvac or occasionally pva homopolymers. Polyvinyl acetate adhesives pvac polyvinyl acetate latex known as white latex is made of vinyl acetate monomer water dispersing agent polymerization starter and other auxiliary materials mixed together through emulsion polymerization.

In fact 80 of all the vam produced in the world is used to make these two chemicals. Poly vinyl acetate poly vinyl acetate pva is a thermoforming resin that is usually water carried and generally used for the wood working and diy industries. 1 acetoxyethylene ethenyl acetate ethenyl ethanoate vac vinyl acetate monomer vinyl ethanoate colorless liquid with a pleasant fruity odor. Polyvinyl acetate a synthetic resin prepared by the polymerization of vinyl acetate.

It is also used in adhesives. Vinyl acetate monomer vam is mainly used in polyvinyl acetate which has applications in water based paints adhesives acrylic fibres paper coatings and non woven binders. In its most important application polyvinyl acetate serves as the film forming ingredient in water based latex paints. Vinyl acetate monomer is mainly used in the production of polyvinyl acetate pvac and polyvinyl alcohol pvoh or pva.

Pvac emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties. Poly vinyl acetate was discovered in germany in 1912 by fritz klatte. Polyvinyl alcohol pvoh used in packaging film and glass laminates is the second largest consumer. Polyvinyl acetate is used in paints adhesives paper coatings and textile treatments while polyvinyl alcohol is used in the production.

Lcs laboratory offers the analysis of poly vinyl acetate for traces of vinyl acetate monomers.
