Permittivity and dipole moment of poly(vinyl pyrrolidone) in chloroform solutions

Abstract

The electrical capacitance of poly(vinyl pyrrolidone), PVP of three different molecular weights (25K, 44K and 700K) in a chloroform solution were measured. The range of concentrations studied for the molecular masses 25K and 44K is (0.1-10w/v%) and that for the molecular mass 700K is (0.1 - 5.0w/v%). All the measurements of PVP solutions were carried out in a temperature range of 25 to 45°C and at 2.0MHz
