What Is Vinyl Acetate Monomer Used For

Vinyl acetate ch 2 cho 2 cch 3 is prepared from ethylene by reaction with oxygen and acetic acid over a palladium catalyst under the action of free radical initiators vinyl acetate monomers single unit molecules can be linked into long branched polymers large multiple unit molecules in which the structure of the vinyl acetate repeating units is.

What is vinyl acetate monomer used for.

In fact 80 of all the vam produced in the world is used to make these two chemicals. 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. Monomers or in premix vessels where a polymerization initiator was dissolved in vinyl acetate monomer previous to its use in the polymerization process. Therefore the study of vinyl acetate bulk polymerization is of great interest from a process safety point of view even if it is not a commercial wide spread process.

Ethylene vinyl acetate eva also known as poly ethylene vinyl acetate peva is the copolymer of ethylene and vinyl acetate the weight percent of vinyl acetate usually varies from 10 to 40 with the remainder being ethylene. Vinyl acetate is the acetate ester of vinyl alcohol. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. Vinyl acetate is a precursor chemical most often used in the manufacture of polyvinyl acetate monomers or polymers similar plastic compounds of low to high molecular weight that can be combined to form other plastics.

Vinyl acetate monomer vam is a key intermediate used in the making of a number of polymers and resins for adhesives coatings paints films textiles and other end products. Vinyl acetate monomer vam is a significant intermediate used in the production of a wide range of resins and polymers for paints coatings adhesives sealants elastomers and a myriad of other industrial and consumer applications. Since vinyl alcohol is highly unstable with respect to acetaldehyde the preparation of vinyl acetate is more complex than the synthesis of other acetate esters. Vinyl acetate monomer is mainly used in the production of polyvinyl acetate pvac and polyvinyl alcohol pvoh or pva.

What distinguishes vinyl acetate monomer from other polymerizable monomers like alkyl meth acrylates and styrene etc. Polyvinyl acetate is used in paints adhesives paper coatings and textile treatments while polyvinyl alcohol is used in the production. Vinyl acetate monomer vam is a colorless liquid organic compound that is the precursor to polyvinyl acetate it is an intermediate used in the manufacture of a number of industrial polymers and resins for the production of adhesives coatings paints films and textiles as well as wire and cable insulation.
