Store at room temperature. Brettanomyces converts this to 4 vinylphenol via the enzyme cinnamate decarboxylase. Pvp is used in electronics as a dielectric layer in organic transistors in organic tft lcd displays. The c o stretching band is very strong in ftir spectra and.

Ch 2 ch c 6 h 4 oh n. Thf lower alcohols dioxane hazards. 4 vinylphenol exists as a solid slightly soluble in water and a very weakly acidic compound based on its pka. 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.

Pmma was found to be miscible with pvph over the entire composition range in the bulk state as a result of a dsc and ftir study. Poly 4 vinylphenol also called polyvinylphenol or pvp is a plastic structurally similar to polystyrene it is produced from the monomer 4 vinylphenol which is also referred to as 4 hydroxystyrene. We examined the composition and molecular weight dependence of the glass transition temperature in detail for two types of hydrogen bonding miscible blends. 4 vinylguaiacol is slightly soluble in water and a very weakly acidic compound based on its pka.
