Polyvinyl alcohol - Wikipedia
网页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.
