内容記述 | The dipole moments of six samples of poly (ethylene oxide) with different molecular weights were determined from dielectric constant and density measurements performed on their dilute benzene solutions over the temperature range from 25 to 55℃. The values of average dipole moment per repeat unit, μ, at 25℃ were 1.061D (M_w=4.6×10^4), 1.063D (M_w=9.5×10^4), 1.041D (M_w=17×10_4), 1.038D (M_w=27×10^4), 1.041D (M_w=57×10^4) and 1.042D (M_w=86×10^4) (D; debye unit, M_w; weight average molecular weight). Different values for μ were obtained, even if the differences remained within a few per cent. The reason for this difference was discussed. The dipole moment ratio was calculated as <μ^2>/nm^2=0.47-0.49 (25℃) and temperature coefficient averaged for six polymer samples was d 1n <μ^2>/dT=1.7×10^<-3>K<-1>. | |||||||||
