Abstract
A three-terminal cell for the dielectric measurement of liquid was made and the cell capacitance was determined using a capacitance bridge. The accuracy of the dielectric constant measurement with the apparatus was examined by measuring standard materials such as benzene and cyclohexane. The mean square dipole moments of poly(p-methoxystyrene) in benzene were determined by accurate measurements of dielectric constants on the polymer dilute solutions and the values were estimated according to two procedures, i.e., one based on Debye and Halverstadt-Kumler equations (DHK method) and the other on Guggenheim and Smith equations (G-S method). The average dipole moments per repeat unit μ were obtained as 1.214 (25°C) and 1.221 (40°C) by the DHK method and 1.204 (25°C) and 1.209 (40°C) by the G-S method (in debye unit). The slight disagreement in μ values obtained by two different procedures was interpreted as arising from differences in assumptions used in the DHK method and the G-S method.
