Polyvinyl alcohol is a man-made or synthetic polymer. PVA polymer molecule contains vinyl and alcohol groups. It is a very useful polymer due to its adhesive properties. PVA is water soluble, crystalline and flammable in nature. Presence of alcohol group in it makes it flammable.

SoarnoL is the trade name of Ethylene-Vinyl Alcohol Copolymer (EVOH) originally developed by Mitsubishi Chemical through years of research. SoarnoL is closely related to Polyvinyl Alcohol (PVOH) which is modified by copolymerizing with ethylene to improve extrudability and water resistance while maintaining most of PVOH's strengths: gas barrier, oil resistance, and transparency.

Polyvinyl alcohol is manufactured by the alcoholysis of polyvinyl esters, in particular polyvinyl acetate, in the presence of a basic catalyst and in the presence of an alkanol as the solvent. The degree of polymerization of the polyvinyl ester used as the starting material is normally within the range from 400 to 10,000. The catalyst used is preferably an alkali metal hydroxide or an alkali ...

In addition, carbon nanotubes (CNTs), graphene oxide (GO), clay, calcium sulfate hemihydrate (CSH), barium sulfate, and some plant fibers [15,16] etc. have also been reported to improve the crystallization of PCL. Polyvinyl alcohol (PVA) is another biodegradable semi-crystalline polymer.

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 precursor molecules known as monomers. Instead, PVA is made by dissolving another polymer, polyvinyl ...

The resulting polyvinyl acetate is hydrolyzed in methanol solution with sodium hydroxide to produce polyvinyl alcohol. By-product methyl acetate that is produced is hydrolyzed to form acetic acid and methanol. The process economics are based on the production of 100 million lb/yr (45,000 metric tons/yr) of polyvinyl alcohol.

Dec 09, 1998· In this case, the plant was recovering polyvinyl alcohol from its fabric desizing process and also wanted to recycle relatively clean bleaching rinse water to the fabric scouring process. The plant was not able to recycle the bleaching rinse water by simply piping it to the scouring operation.

Poly(vinyl 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 PVAc adhesive formulations, in a variety of coatings, and 3D printing.It is colourless (white) and odorless. It is commonly supplied as beads or as solutions in water.
