Poly(p-hydroxystyrene) Usage And Synthesis

Chemical Properties	Tg 136°C
Uses	Poly(4-vinylphenol) is used as an antimicrobial surface coating in mutilayered film.
Uses	Poly(p-hydroxystyrene) can substitute for Novolac resins in photoresists, adhesion promoter and improves heat resistance in hot melt adhesives and surface treatment in metal finishing. Derivatives used as antioxidants and flame retardants in plastics. Component of polymer blends to modify surface characteristics and improve impact resistance.
General 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.
