Vinyl Acetate Monomer Uses

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.

Vinyl acetate monomer uses. Polyvinyl alcohol pvoh used in packaging film and glass laminates is the second largest consumer. 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. 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. Vam can be polymerized in mass solution suspension or emulsion.

Vinyl acetate monomer imports by india 2004 2016 in mt figure 5. 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. In fact 80 of all the vam produced in the world is used to make these two chemicals. 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.

Vinyl acetate monomer production and demand 2008 2016 mt figure 2. What distinguishes vinyl acetate monomer from other polymerizable monomers like alkyl meth acrylates and styrene etc. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. Vinyl acetate monomer vam is used for the production of polymer emulsions of various types which are base resins for water based paints adhesives paper coatings and textile finishes.

Vam import sources india 2014 figure 6. Vinyl acetate is primarily used as a monomer in the production of polyvinyl acetate and polyvinyl alcohol 1 vinyl acetate is also used as a raw material in the production of other chemicals in adhesives water based paints nonwoven textile fibers textile sizings and finishes paper coatings inks films and lacquers. 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. Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl acetate monomer value per ton 2001 2016 mt figure 4. Vam imports share 2015. 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.
