Poly(4-vinylphenol) [MW ~22,000]

Poly(4-vinylphenol) (PVPh), also known as poly(4-hydroxystyrene), is a phenol-functional vinyl polymer with hydroxyl groups on the aromatic rings. This grade has an approximate molecular weight of 22,000 and a polydispersity of approximately 5. Synonyms: Poly(4-hydroxystyrene); PVPh. The phenolic hydroxyl groups participate in hydrogen bonding and other specific intermolecular interactions. Poly(4-vinylphenol) is used in photoresist and thin-film patterning research and is also widely studied in polymer blends where hydrogen bonding influences miscibility and phase behavior. Key Properties Polymer: Poly(4-vinylphenol) (PVPh) Product number: 18980 CAS number: 24979-70-2 Approximate molecular weight: ~22,000 Polydispersity: ~5 Linear formula: [-CH2CH(C6H4OH)-]n Glass transition temperature (Tg): 150°C Form: Powder Storage temperature: Room temperature Applications Photoresist & Lithography Research Poly(4-vinylphenol) is used as a phenolic polymer in photoresist systems. Its hydroxyl-functional aromatic structure is relevant to resist chemistry and lithographic materials research. Thin-Film Patterning The ~22,000 MW Polysciences grade has been used as a polymer resist in thin-film patterning research, including patterned thin-film transistor fabrication. Polymer Blend & Hydrogen-Bonding Studies PVPh is frequently studied as a hydrogen-bond-donating polymer in investigations of polymer miscibility and specific intermolecular interactions. Solubility & Compatibility Poly(4-vinylphenol) is soluble in tetrahydrofuran (THF), lower alcohols, and dioxane. The phenolic hydroxyl groups can form hydrogen bonds with complementary functional groups in other polymers, making PVPh useful in studies of hydrogen-bonded polymer blends.
