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


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).
