摘要：

Broadband dielectric spectroscopy covering the frequency range from 10 _1 Hz was used to analyse the softmode at the phase transition from a ferroelectric highly ordered and tilted smectic phase to the smectic A —phase in a combined side group main chain liquid crystalline polymer. © 1990, Taylor & Francis Group, LLC.
