Explanation
It is a white powder, flake or flocculent solid water soluble polymer polymer, whose performance is between plastics and rubber, and the glass transition temperature is 60-85 ° C. Because the monomer of vinyl alcohol is unstable, polyvinyl alcohol cannot be prepared from monomer vinyl alcohol. It can only be obtained by partial or complete hydrolysis of polyvinyl acetate.
