Application:
Polyvinylpyrrolidone k30 is widly used in pharmaceutical field , and it is one of medicinal synthetic excipients, mainly used as glidants for sustained-release injections and stabilizers.
Physical properties:
1.Solubility and solution characteristics:
Polyvinylpyrrolidone k30 is soluble in a variety of organic solvents, so it has a wide range of applications in the production of membranes in water. It is an excellent membrane porogen. Taking PVDF hollow fiber as an example, Polyvinylpyrrolidone k30 /PVDF and other fillers are dissolved in organic solvents such as DMF or DMAc to form membrane filaments with uniform pore size.
2.Surface activity:
The environment at both ends of the dipole amide group in the molecule is not the same. From the molecular model, the oxygen atom is exposed, while the end containing the N atom is just surrounded by the methyl group and the methylene group. in. The molecular structure of Polyvinylpyrrolidone k30 gives it surface activity and can be used as a polymer surfactant.
