Application

PVP (average mol wt 10,000) can be used as a stabilizing agent in the synthesis of metal nanoparticles to prevent them from agglomeration. PVP is also used in the fabrication of mesoporous silica-polymer hybrid (PVP-aminopropyl-SBA-15 Schiff Base hybrid) for the effective removal of divalent heavy metal cations from wastewater. Grafting of PVP functionalization offers a strong affinity for heavy metal ions because it provides two adsorption sites, one through metal-C-O group interaction and the other through metal-π interaction (the chelation of with Schiff base).

General description

Polyvinylpyrrolidone (polyvidone, povidone, or PVP) is a synthetic water-soluble polymer consisting of linear 1-vinyl-2-pyrrolidinone groups. It is hygroscopic and readily absorbs up to 40% of water by its weight. It has excellent wetting properties in solution and easily forms films, which makes it suitable for use as a coating additive.PVP can be synthesized from its monomer N-vinylpyrrolidone via free-radical polymerization in the presence of AIBN as an initiator. In chemical industries, PVP is widely used as a surface stabilizer, growth modifier, nanoparticle dispersant, and reducing agent.

PVP can serve as a surface stabilizer, nanoparticle dispersant, growth modifier, and reducing agent, depending on the synthetic conditions.

Other Notes

Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution.

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. How can solutions of Product PVP10, Polyvinylpyrrolidone, be kept?

    Sterile solutions can probably be kept at room temperature for several months.

  6. What is the K value in the specification of Product PVP10, Polyvinylpyrrolidone, and how is it determined?

    Polyvinylpyrrolidone (PVP) is characterized by its K value, a dimensionless value which is a function of the average molecular weight, the degree of polymerization, and the intrinsic viscosity.  It is calculated from dilute solution viscosity measurements.  log (Ns/No)/C = (75 Ko x Ko)/(1 + 1.5 Ko C) + Ko where Ns = viscosity of the solution, No = viscosity of the solvent and C = concentration in grams per 100 ml of solution. K = 1000 x Ko. The larger the K value for a material, the higher the viscosity.  

  7. What solvents can be used to dissolve Product PVP10, Polyvinylpyrrolidone?

    This compound is readily soluble in water.  It has also been reported in the chemicals encyclopedia published by the Royal Society of Chemistry, 12th ed., Entry# 7879 to be soluble in ethanol and chloroform, but practically insoluble in ether.
