Physical properties:
Solubility:
PVP is a water-soluble polymer, which is miscible with water and can be dissolved in many organic solvents such as alcohols, carboxylic acids, amines, and halogenated hydrocarbons.
Film-forming properties: PVP has very good film-forming properties. PVP can be cast or coated to form a film when dissolved in some solvents such as water, methanol, ethanol, etc.
Water absorption:
PVP has strong water absorption and moisturizing properties, and is often used in cosmetics.
Dispersibility and solubilization: Small molecule PVP has a good dispersing effect, preventing particles from agglomerating and precipitation. PVP can increase the solubility of many substances in aqueous solutions.
Complexity:
O atoms in the PVP molecule. The N atom is a typical coordinating atom, which enables it to complex with certain substances, such as iodine, benzene, amorpholine and various sulfonamides.
Application:
Adhesive: PVP has good viscosity and is used as an adhesive in solid glue sticks, stamps, band-aids, plaster bandages, etc.
Coatings and inks: PVP has excellent dispersing properties. The coatings added with PVP increase viscosity, improve coloring power, eliminate floating phenomenon, disperse and stabilize pigment components, improve gloss, and avoid pigment flocculation and precipitation.
