Vinyl Ester Monomer

Veova monomer products include.

Vinyl ester monomer.

In vinyl ester polymerization the very different reactivities of the growing radicals high and the monomer low result in a high level of chain transfer reactions and main chain irregularities which make the production of uniform polymers rather difficult. Veova 10 vinyl ester homopolymer. Vinyl alcohol containing polymers are prepared by hydrolysis of the corresponding vinyl acetate polymers. Vinyl esters undergo homopolymerization via a radical mechanism.

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. Veova 10 monomer is the vinyl ester of neodecanoic acid 10 carbon atoms and has a homopolymer tg of 3 c making it a flexibilizing monomer. Veova eh monomer is the vinyl ester of 2 ethylhexanoic acid a more linear acid and therefore has a significantly lower tg of 36 c. An industrially important example is vinyl chloride precursor to pvc a plastic.

The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst. This structure is also available as a 2d mol file or as a computed 3d sd file the 3d structure may be viewed using java or javascript. Acetic acid vinyl ester. Vinyl acetate is not as hydrolytically stable in polymers as are the structurally similar acrylic esters.

Veova 9 vinyl ester homopolymer tg 70 c. Xtxrwkrvritetp uhfffaoysa n cas registry number. They are increasingly used in radiation curing systems because of a lower toxicity profile than the commonly used acrylic monomers. Acetic acid ethylene ether.

Ethanoic acid ethenyl ester. Vinile acetato di vinylacetaat dutch vinylacetat german vinyle acetate de octan winylu polish acetic acid vinyl ester. Vinyl ethers undergo homopolymerization via a cationic mechanism. Vinyl acetate is the acetate ester of vinyl alcohol.

Vinyl ester resins are the binary resin systems containing a dimethacrylate monomer from which the cured material gains most of its properties and a reactive monomer such as styrene which acts as a reactive diluent and also takes part in the cross linking reaction. Advances in fire retardant materials 2008. The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. The most widely used member of the category is vinyl acetate.

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics.
