WebGeneral description. Poly (4-vinylphenol) (PVP) is a polymeric cross-linker mainly used as a layer to improve adhesion by forming a non-toxic and low cost film. It is an acidic polymer which consists of more than 100 hydroxyl groups in one molecule of PVP which result in high stability and complexation of the films.
