Products Description of Poly(vinyl alcohol) CAS#9002-89-5
Polyvinyl alcohol (PVA) is a solid available in the form of white powder, flakes, or flocs, with a glass transition temperature ranging from 60 to 85°C. Rich in hydroxyl groups, it exhibits polarity and can form hydrogen bonds with water, enabling solubility in polar water. Additionally, PVA is soluble in hot hydroxyl-containing solvents such as glycerol and phenol, but insoluble in common organic solvents like methanol, benzene, acetone, and gasoline.
