Products Description of Poly(vinyl alcohol) CAS#9002-89-5
Polyvinyl alcohol is a solid that can be in the form of white powder, flakes or flocs. The glass transition temperature is 60-85°C. Polyvinyl alcohol contains many alcohol groups, is polar, and can form hydrogen bonds with water, so it can be dissolved in polar water. Polyvinyl alcohol can also be dissolved in hot hydroxyl-containing solvents such as glycerol and phenol, but is insoluble in general organic solvents such as methanol, benzene, acetone, and gasoline.
