polyvinylpyrrolidone cross linked solubility

The solubility parameters of polyvinylpyrrolidone are about 9.1~10.6(J/cm*) 12. Polyvinylpyrrolidone is a white to light yellow amorphous delixing powder with excellent water solubility, excellent chemical stability and good biocompatibility.

Solubility of polyvinylpyrrolidone in water
Polyvinylpyrrolidone is insoluble in water at room temperature, but can partially dissolve with water at high temperatures.
I. Polyvinylpyrrolidone
Polyvinylpyrrolidone (PEP or PVP) is a polymer that is a linear polymer polymerized from vinylpyrrolidone monomer. It has good biocompatibility, dispersion, adhesion and surface activity, and is widely used in medicine, cosmetics, food and other fields.
Second, the solubility of polyethylene pyrrolidone in water
Polyvinylpyrrolidone is a hydrophilic polymer, but it is not easily soluble in water at room temperature. However, as the temperature increases, the force between Pvinylpyrrolidone and water decreases, so it can partially dissolve with water at high temperatures. According to different literature records, the solubility of polyvinylpyrrolidone at 20℃ is 0.01-0.05g/100mL, and the solubility can be increased to about 10g/100mL at 50℃.
3. Factors affecting the solubility of polyethylene pyrrolidone
In addition to temperature, several other factors can also affect the solubility of polyvinylpyrrolidone in water. Among them, the molecular weight, polymerization degree, hydrophilicity and other properties of polyethylpyrrolidone will affect its solubility. In addition, the pH value and ionic strength of polyvinylpyrrolidone also have a certain effect on its solubility in water. It is worth noting that these factors may have different effects on different polyethylpyrrolidone products, so it needs to be considered in combination with the actual situation when using them.

Polyvinylpyrrolidone is an important polymer compound, which has been widely used in many fields. Understanding the solubility of polyvinylpyrrolidone at different temperatures and the factors affecting its solubility can provide a certain reference for the research and application in related fields.
