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 .
The most common side effect of artificial tears is ... Similarly to human ... were more effective in treating dry eye symptoms over 1.4% polyvinyl alcohol-based tears
The thin wrapping portion of the pod which contains the liquid detergent is made from PVA, a dissolvable form of plastic also known as polyvinyl alcohol. This same PVA coating is also used in ...
Pharmacokinetic studies in humans and various laboratory animal models indicate no to very little systemic absorption of PVP following oral administration. [ 6 ] PVP added to iodine forms a complex called povidone-iodine that possesses disinfectant properties. [ 7 ]
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 ]
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] Like many plastics, it is difficult to biodegrade. One study suggested ...
Polyvinyl acetate (PVA) Includes white glue (e.g. Elmer's Glue) and yellow carpenter's glue (Aliphatic resin) (Brands include Titebond and Lepage) Polyvinyl alcohol; Polyvinyl chloride (PVC) Polyvinyl chloride emulsion (PVCE) – a water-miscible emulsion that polymerizes as it cures; Polyvinylpyrrolidone (component of glue sticks) Silicone resins
Vinylon, also known as Vinalon (more common in Korean sources), is a synthetic fiber produced from reaction between polyvinyl alcohol (PVA) fiber and formaldehyde. Chemically it is polyvinyl formal (PVF). Vinylon was first developed in Japan in 1939 by Ri Sung-gi, Ichiro Sakurada, and H. Kawakami. [1]
