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 ]
Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
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 .
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.

Its molecular structure consists of a vinyl group (−CH=CH 2) linked to a nitrile (−C≡N). It is an important monomer for the manufacture of useful plastics such as polyacrylonitrile. It is reactive and toxic at low doses. [5] Acrylonitrile is one of the components of ABS plastic (acrylonitrile butadiene styrene). [6]
Vinyl acetate is an organic compound with the formula CH 3 CO 2 CH=CH 2. This colorless liquid is the precursor to polyvinyl acetate , ethene-vinyl acetate copolymers , polyvinyl alcohol , and other important industrial polymers.
The preparation of vinyl esters typically requires indirect methods because vinyl alcohol is not a suitable reagent. Vinyl acetate, which is available on an industrial scale, can be used to produce other vinyl esters. The process is sometimes referred to as transvinylation. [10] Higher esters of vinyl acetate have been used in the synthesis of ...
