Vinyl Ester Monomer

Vinyl alcohol containing polymers are prepared by hydrolysis of the corresponding vinyl acetate polymers.

Vinyl ester monomer.

The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms. 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 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. Vinyl acetate is not as hydrolytically stable in polymers as are the structurally similar acrylic esters. Advances in fire retardant materials 2008.

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. Veova 10 vinyl ester homopolymer. 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. The major industrial route involves the reaction of ethylene and acetic acid with oxygen in the presence of a palladium catalyst.

Vinyl ethers undergo radical initiated copolymerization in the presence of specific monomers such as maleates fumarates and acrylics. Emulsion polymers based on veova vinyl ester show clear improvement in scrub resistance and can be used for high quality low voc interior paints exterior paints industrial coatings as well as redispersible powders for dry mix mortars. Vinile acetato di vinylacetaat dutch vinylacetat german vinyle acetate de octan winylu polish acetic acid vinyl ester. An industrially important example is vinyl chloride precursor to pvc a plastic.

In chemistry vinyl or ethenyl abbreviated as vi is the functional group with the formula c h ch 2 it is the ethylene iupac ethene molecule h 2 c ch 2 with one fewer hydrogen atom. Acetic acid vinyl ester. The most widely used member of the category is vinyl acetate. Veova monomer products include.

Vinyl acetate is the acetate ester of vinyl alcohol. 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. 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. Vinyl ethers undergo homopolymerization via a cationic mechanism.

Ethanoic acid ethenyl ester.
