The monomer of polyvinyl alcohol was described in Example Problem7.6. A small section of the resulting polymer as a line diagram should be depicted. Concept introduction: Polymers are made up of monomers, all linked together to form long chain of repeated units of monomers. Poly vinyl alcohol is a water soluble synthetic polymer . It is used in paper making. The monomer is vinyl alcohol.
