Popis:	Dielectric response, from 1 Hz to 10 MHz, of liquid crystalline side chain elastomers has been compared to the one of analogous uncrosslinked materials. Results are discussed in terms of mobility of the mesogens. Two different systems have been investigated: smectic A elastomers allow to determine the influence of crosslinking on the ∂ relaxation (i.e. the reorientation of the whole mesogen around the chain), a SC* elastomer shows the drastic influence of the polymer network on the Goldstone mode.
