  • Polyvinyl alcohol chemical compound Britannica

    Instead, PVA is made by dissolving another polymer, polyvinyl acetate (PVAc), in an alcohol such as methanol and treating it with an alkaline catalyst such as sodium hydroxide. The resulting hydrolysis, or “alcoholysis,” reaction removes the acetate groups from the PVAc molecules without disrupting their long-chain structure.

  • Polyvinyl Alcohols - an overview ScienceDirect Topics

    Polyvinyl alcohol (PVA) is the hydrolysis product of polyvinyl acetate. Depending on the hydrolysis conditions, there are fully hydrolyzed PVA and partially hydrolyzed PVA as shown in Fig. 5.4(a) and (b) respectively. Fully hydrolyzed PVA usually has a degree of hydrolysis (DS) of 98% to 99.8%, and can dissolve in water only at > 80 °C.
