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

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.

2014年1月28日 · What it is: Polyvinyl alcohol is a synthetic polymer, which is a substance made up of many, many molecules all strung together. It starts its life as ethylene, a natural gaseous hormone given off by plants that causes the fruit to ripen.

Vinyl alcohol is also called ethanol with the chemical formula (CH 2 CHOH). A functional group having the formula H - C = CH 2 is called the vinyl group. It has one hydrogen atom less than ethene. When a hydroxyl group is attached to the vinyl group, vinylic alcohol is alcohol is formed. Vinyl alcohols are generally unstable in nature.

2024年6月30日 · Polyvinyl alcohol, aka PVA, PVOH or E1203, is a synthetic plastic polymer. In our homes, it’s most commonly found as the thin wrapping around dishwasher and laundry pods. It’s also woven into disposable laundry sheets to keep them intact.

2024年12月7日 · Polyvinyl alcohol (PVA), a colourless, water-soluble synthetic resin employed principally in the treating of textiles and paper. PVA is unique among polymers (chemical compounds made up of large, multiple-unit molecules) in that it is not built up in polymerization reactions from single-unit

2024年5月21日 · Polyvinyl alcohol or PVA (sometimes also called PVOH or PVAl) is a class of water-soluble synthetic (manufactured) polymers primarily derived from fossil fuels.

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.
