Properties
Keywords Hydrophilic Polymers, Hydrophobic Polymers, Materials Science, Poly(vinylpyrrolidinone) (PVP), Poly(vinylpyrrolidinone) (PVP) and Copolymers, Poly(vinylpyrrolidone), Polymer Science, Polymers, Vinylpyridine and Vinypyrrolidone Polymers
Key Applications Thickeners
Dispersing agents
Detoxicant
Complexing agent
Product Type Biochemicals
Density 1.23-1.29 g/mL(Lit.)
Viscosity 27 - 35 cps(1% aq soln)
Presentation White Powder
Format Powder
pH 2.8 - 4.2(5% aq soln)
Detection Method FTIR
Solubility Soluble in water(> 100 mg/mL, 2.5% aq solution), methanol, ethanol, alcohol, chloroform and glycerol, acetic acid; insoluble in dimethyl ether, ethyl acetate, acetone, toluene, xylene, mineral oil, carbon tetrachloride. If the pH value of the solutions is higher than 6, the viscosity will increase slightly on storage, particularly at elevated temperatures; if the pH value is less than 7 and the concentration is lower than 30%, the solutions tend to become moldy during storage. The addition of a preservative can prevent mold and fungus growth during storage. Addition of large quantities of salts will precipitate the PVP from solution.
Storage & Handling Store at Room Temperature(15-30 °C).
