The dielectric spectroscopy of polydimethylsiloxane is measured in temperature range of 190 to+120℃ The variation of frequency domain dielectric constant is very small, but time domain slow dielectric constants have high peaks at 120 and +80℃. According to H31 structure of molecule, the results can be explained. The time domain method can detect trace impurity of water to2×10-7 in polydimethylsiloxane.
