The a-relaxation of a linear poly(methylhydrogensi1oxane) has been investigated as a function of temperature and frequency using dielectric relaxation spectroscopy. Replacement of the hydrogen with a hexyl group increased the temperature and broadness of the a-process, and this is interpreted in ter

β¦ Synopsis
The NhfR and dielectric relaxation data on the isotropic melt of F]-azosyaniwole hove been snaIy:ed in terms of conventional rcI;isation theories. The observed discrepancies are interpreted by considering the reorientation ot'the methoxy end groups. NMR results are used to evaluate the "retardation factor" related to the low frequency ~&ion of the dielectric dispersion in the nematic mesophnse
