The solubility parameter of poly(vinylpyrrolidone)


Polimery 1982, No 11, 427



DOI: dx.doi.org/10.14314/polimery.1982.427

Summary

The solubility parameter of poly(vinylpyrrolidone) (PVP) has been determined by the methods of limiting viscosity number and swelling measurements. Both methods led to practically identical results of 25.6 (J/cm3)1/2. After splitting the solubility parameter into the dispersion and polar components, the solubility area of PVP has been established. The two-component model of the solubility parameter has been applied to the mixtures of PVP with poly(acrylonitrile) and poly(acrylamide).
