Broadband dielectric spectroscopy (10−1 Hz — 109 Hz) was used to study the collective and molecular dynamics in polymeric side-chain FLC. In the frequency window under study collective (Goldstone-mode) and molecular (β-relaxation) relaxations are observed. By crosslinking combined main-chain side-group polymers an elastomeric FLC can be prepared which exhibits a Goldstone-mode as well. The piezoelectricity in these elastomeric materials is experimentally proven.
