    en.wikipedia.org/wiki/Polyvinyl_alcohol

    Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH 2 CH(OH)] n. It is used in papermaking, textile warp sizing, as a thickener and emulsion stabilizer in polyvinyl acetate (PVAc) adhesive formulations, in a variety of coatings, and 3D printing. It is colourless (white) and odorless.

    Vinyl alcohol, also called ethenol (IUPAC name; not ethanol) or ethylenol, is the simplest enol. With the formula C H 2 CH O H , it is a labile compound that converts to acetaldehyde immediately upon isolation near room temperature. [ 1 ]

  4. Ethylene vinyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Ethylene_vinyl_alcohol

    Ethylene vinyl alcohol (EVOH) is a formal copolymer of ethylene and vinyl alcohol. Because the latter monomer mainly exists as its tautomer acetaldehyde , the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate (EVA) copolymer followed by hydrolysis.

  5. Vinyl polymer - Wikipedia

    en.wikipedia.org/wiki/Vinyl_polymer

    Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")

  9. Ethylene-vinyl acetate - Wikipedia

    en.wikipedia.org/wiki/Ethylene-vinyl_acetate

    Polyethylene vinyl acetate has recently become a popular alternative to polyvinyl chloride because it does not contain chlorine. [13] As of 2014, EVA has not been found to be carcinogenic by the NTP , ACGIH , IARC , or OSHA , and has no known adverse effect on human health. [ 14 ]
