Product Description. Ashland polyvinylpyrrolidone (PVP) polymers are used in hair styling applications for their ability to form clear, hard, glossy films. In addition, PVP also stabilizes emulsions, dispersions and suspensions. PVP is soluble in water and many organic solvents. They are available in a range of viscosities and supplied as either. Like all free radical polymerization products, PVP has a typical Schulg-Ftory molecular weight distribution. As the high molecular weight PVPK90 in the PVP series, its molecular weight distribution curve is usually wider, because of the higher molecular weight, which usually becomes Many branches As a food additive, PVP is a stabilizer and has E number E1201. PVPP (crospovidone) is E1202. It is also used in the wine industry as a fining agent for white wine and some beers. In molecular biology, PVP can be used as a blocking agent during Southern blot analysis as a component of Denhardt's buffer. It is also exceptionally good at absorbing polyphenols during DNA purification

Influence of Polymer Molecular Weight on Drug-polymer

PVP is widely used and has been approved by the U.S. Food and Drug Administration (FDA) for several purposes, such as a coating agent, polymeric membrane, and material for controlled drug release.18 Furthermore, PVP has also been used for a long time as a blood plasma expander in a clinical setting.19 In addition, PVP with a molecular weight of. PVP can promote the nucleation of metallic Ag because Ag ions are easily reduced by the lone-pair electrons of PVP []. Thus the significantly higher molecular weight of PVP K90 has given it more chances to form a complex with Ag ions than PVP K30. Thus the sizes of Ag@PVP90 particles are fairly higher than those of Ag@PVP30 (hydroxypropyl methyl cellulose 2910), PVP-K90 (polyvinylpyrrolidone-K 90), PVA (polyvinyl alcohol, molecular weight 31,000-50,000)]을 도 입하여 (+)-dihydromyricetin의 입자크기를 줄일 수 있는지를 조사 하였다. 즉, 분별침전 시 고분자 물질의 종류와 농도를 달리하여 Models: Products are classified according to their K-values, which was calculated based on polymer molecular weight & viscosity of PVP solution.
