| Popis: | The permittivity of the following mixtures has been measured at 20°C between 30 MHz and 72 GHz: PEG 400 with toluene or PEG 400 dimethylether (PEGDM); PEG 200 with ethyleneglycolmonomethylether, ethyleneglycol, ethanol, methanol or water. The description of the dielectric spectra ranges from an apparently unperturbed superposition of contributions from both mixture components (PEGPEGDM) to the occurance of strong additional contributions (PEGH2O) which are ascribable to heteroassociation. |
