heal.abstract	Ferroelectric polyamide 11 films were prepared by melt-quenching, cold-drawing and electrical poling. Ferroelectricity was checked by dielectric-hysteresis measurements. Dielectric spectroscopy was applied for determining piezoelectric constants from thickness-extension resonances as well as for investigating conformational changes due to quenching, stretching and electrical poling. A remanent polarisation of up to 35 mC/m2, a coercive field of 75 MV/m and a piezoelectric d33 coefficient of 2.7 pC/N were obtained. In the ferroelectric film, the dielectric α relaxation is suppressed whereas the β relaxation is enhanced.	en
