Abstract
Time-resolved FTIR-spectroscopy is employed to study structure and mobility in ferroelectric LC polymers and elastomers (temperature range 20 degrees C...130 degrees C, dynamic range 0.1 Hz...10(5) Hz). Due to its specifity t he analysis of the (polarized) IR-spectra enables to determine the average orientation, the orientational order and the mobility in response to an ele ctric field for the different molecular moieties (phenyl group, the polar g roups, the methylene spacer and the polymer backbone). Furthermore the phas e relationship in the motion of the different molecular groups can be extra cted.
