| 520 | |b 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. The dielectric parameters such as static permittivity, increment of permittivity and dipole moment were calculated and their variation with concentration, temperature and molecular weight was discussed. It is found that the static permittivity, the increment of permittivity and the dipole moment of PVP solutions increase as the concentration and molecular weight of PVP increase but decrease as the temperature increases. | ||
