2. Polyvinyl acetate - Wikipedia

   en.wikipedia.org/wiki/Polyvinyl_acetate

   Polyvinyl acetate is also the raw material to make other polymers like: Polyvinyl alcohol −[HOCHCH 2 ]−: Polyvinyl acetate is partially or completely hydrolysed to give polyvinyl alcohol. This reversible saponification and esterification reaction was a strong hint for Hermann Staudinger in the formulation of his theory of macromolecules .

7. Adhesive bonding - Wikipedia

   en.wikipedia.org/wiki/Adhesive_bonding

   Pre-treatment can be used to modify surfaces in a targeted way and thus make them more adhesive. [3] In addition to coating the substrates with an adhesion promoter to enable good adhesion, surfaces can also be modified by various methods to prepare them for gluing. The most common surface pre-treatment methods are listed in the adjacent figure.
