What Is Vinyl Acetate Monomer Used For

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.

What is vinyl acetate monomer used for. 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. 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. There are three different types of eva copolymer which differ in the vinyl acetate va content and the way the materials are used. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

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. Polyvinyl alcohol pvoh used in packaging film and glass laminates is the second largest consumer. 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. Monomers or in premix vessels where a polymerization initiator was dissolved in vinyl acetate monomer previous to its use in the polymerization process.

In fact 80 of all the vam produced in the world is used to make these two chemicals. The largest derivative is polyvinyl acetate pva which is mainly used in adhesives as it has good adhesion properties to a number of substrates including paper wood. 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. 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.

What distinguishes vinyl acetate monomer from other polymerizable monomers like alkyl meth acrylates and styrene etc. Vinyl acetate is the acetate ester of vinyl alcohol. 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.
